Withholding  of the movements of the thought  with conscience in mental health by  the life being s is called the spiritual union ( Yoga). To finish  the movements of the thought  with sense of right and wrong  in mental health  requires  the spiritual union ( Yoga).

Spiritual union in the yoga requires that thoughts with conscience in mental health should be nullified and the thought process come to an end. The method of come to an end of the wheel and helm of thoughts with conscience is called spiritual union in yoga. Self realization is possible through this perfect method of come to an end the thought process. The true self  is realized through the knowledge of one’s thoughts with the sense of the right and wrong  in mental health. True Self and its thoughts realization leads to interior God essence realization.

It is impossible to realize the supreme  self of the life force  of formless Interior God essence, without the knowledge of one’s own self. Take any religion practice. Ask any sage or seer, who has realized his self and the sense of the right and wrong  in mental health and who has felt the interior vision of interior God essence. It will be confirmed that self and the sense of the right and wrong  in mental health realization  is outer part of interior soul essence and interior God essence realization.

How can a person know conscience of others life being  when he has not realized conscience of his own self ? How can a person be conscious of the existences of other life being s in universe, when he has no conscience about his own true existence? The connection between a true life being s and interior God essence is only through the interior soul essence of all  life being s in universe. The connection of the vast universe with interior God essence is also through the endless and limitless interior soul essence.

Hence, for interior God essence realization, the first step is realization of self and its conscience. The preceptor says that so long as life being s does not have awareness of his own self and its conscience, all his recitation of interior God essence’s name and obeisance to interior God essence and meditation in simple mind will be fruitless. His efforts in this direction will be fruitless. These efforts get erased from simple mind of life being s after death. According to the preceptor, sage Patanjali, self realization can be achieved, by finishing the vagaries of thought and by come to an end the thought process with conscience in mental health. self and its conscience realization is not possible without knowledge of the working of the  thoughts of the simple mind. The knowledge of the working of the simple mind is not possible without the knowledge of thoughts.

So long as knowledge of thought is not acquired, thoughts cannot be come to an end. The efforts to come to an end and still the thoughts by the method of spiritual union with yoga and obtaining knowledge of the working of the mind and interior soul essence and interior God essence are called spiritual union with yoga. Thus the preceptor, in one go, offers the key to interior God essence realization. This realization is not to be attained from outside matter world forms or in spiritual thesis or from saints or sages. Neither it is to be attained from any thesis of religious books, nor from any  thesis of teacher or thesis of the preceptor. Further, this realization cannot be cultivated or produced or made it self. It is already within one’s own interior self  and is inborn and hence, can only be realized through the understanding and knowledge of one’s self and its conscience that is outer part of interior soul essence and is true self.

Its account is written by interior nature essence’s benevolent hand. This knowledge is the supreme knowledge of interior God essence. This is the knowledge, which is behind the creation of all life and death cycle in all life being  in universe All the creatures animate and inanimate, big and small of universe are born and created with the help of each other in & by same interior and formless nature essence. They live and die and become food for each other in same nature essence, according to cosmic power of inter dependence of cosmic knowledge.

The cosmic power of interior nature essence is playing its game and changing the creation’s face with the help of this cosmic knowledge. Nothing ever is destroyed in interior nature essence. Whatever happens in the universe denotes the changing face of interior nature essence. The key for initiation into the supreme knowledge of interior God essence is to come to an end the wheel of imagination and halt the vagaries of mind through spiritual union of yoga. Feeling layers of conscious in mental health enlightens the mind. This is achieved by come to an end the thought process and by stopping the wheel of imagination in interior formless mind of life being s.

What is that does thinking? life being s is the highest and lowest creation of interior God essence .The interior soul essence of all life being s is alike rather is one. The truth is that they are the life being  infestations of one Supreme Being. This interior soul essence is surrounding part of the one formless interior God essence. They are the sparks of interior God essence’s cosmic power. They are means of outer reflecting and radiating interior God essence’s storehouse of interior power, which have created the outer matter world. The outer matter world of universe has unlimited forms and planets of forms. The individual interior soul essence is the means to have a vision of interior God essence’s creation. They are the means to feel calmness, peace, happiness, serenity, and bliss, as they reflect a vision or vision of interior God essence.

Of all the life being , human being's life is the highest and lowest creation of universe. While human beings life have greater state of conscience in mental health, the interior soul essence enjoys a greater freedom of movement. When a life being s lives in a state of conscience of mental health, he resides in his formless interior soul essence. He leads a life of serenity with the help of true knowledge. When a life being s lives in  unconscious  state of mind, he resides in the animate or inanimate creation of matter world of universe and is outside even his matter body. Deluded and with imaginary knowledge in brain that is outer part of unconscious mind, he is involved in seeking happiness. As such, instead of attaining true happiness, he leads a miserable life full of sorrow or imagined happiness of thoughts of unconscious mind.

Constantly and unconsciously thinking of other endless creatures and forms of universe with endless desires, he exposes himself to the operative system of karma of interior nature essence that write fruits of desires in thoughts of unconscious mind, according to the cosmic power. The sage Patanjali says that if a life being s consciously focuses his entire attention on Interior God essence and tries with full courage and determination to establish Yoga music with Interior God essence, the cosmic interior operative system of interior interior nature essence, not only rids him of his thoughts but also come to an ends the onslaught of sorrows, miseries and grief's. After the realization of such knowledge, he experiences serenity and vision of interior God essence.

Guru Patanjali says that through spiritual union of yoga technique and by constant and repeated practice and efforts, it is possible to have realization of interior God essence’s vision in one single life span. Once a life being s attains interior God essence realization, he enters a state of contentment. He learns the technique of taking the form of life of his choice. This is called salvation and liberation or seedless spiritual union of yoga. This is the goal of life being 's life, which one secures after many life being s lives. A life being s, who realizes Interior God essence, also realizes the feeling of interior soul essence that is true self. He keeps on experiencing and realizing the separate entity of his interior soul essence more than that of his matter body and subtle mind.

What is life being 's body? life being 's body like bodies of other living creatures is a cosmic instrument. In it, interior formless nature essence has put a life being , according to its past karma actions and for a definite period, to reap the fruits of its past karma actions. The living human matter body and sense organs that is eyes, ears, nose, tongue or skin does nothing by its self. The interior soul essence by itself also does nothing. Whatever happens inside or outside the matter body of life being  is witnessed by the interior soul essence through its conscience of mental health.life being 's conscience of mental health which functions under the operative system of cosmic power of interior nature essence, keeps an account of life being 's actions and deeds, and the fruits of action reaped and is ever active even during sleep from birth to death.

The human unconscious mind keeps on experiencing joy and sorrow of matter world that are the outcome of its actions and it keeps on sowing the seeds of future actions and the seeds it sows, are according to the thoughts and desire in it passing through it. The practice and technique of stopping the sowing of the seeds of thought and desires, the thought of worldly sorrow and joy, thought and desire of reaping the fruits of karma action, thoughts or desiring of enjoying the comforts of the material world, in conscience of mental health is called spiritual union with yoga by sage Patanjali.

What is individual living cell? When a life being s or any other life being  body is fragmented and broken into pieces, the last living cell found in it, is called the individual living cell. This cell has no further living cells in it. The life being s body is a mixture of millions of individual living cells. All these individual living cells have all those attributes, all those traits and action oriented qualities, which a complete life being s has. Thus each individual living cell has the possibility of becoming a complete life being s. Modern science supports that this living cell is composed of five material elements, which are earth, water, air, fire, and light. It is also a mixture of five subtle elements, which are smell, sound, taste, sight and touch. The outer shape of these individual life being  cell forms is comprised of material mixture elements and its interior shape is comprised of these subtle elements mixture. Each individual living cell contains an unending stock of the cosmic power of Interior interior nature essence, which is formless, eternal and infinite.

The formless, shapeless, timeless and unending stock of cosmic power of interior interior nature essence that is outer part of soul is forever, which is the residence of Interior soul essence. Interior soul essence resides in the interiormost core of the individual living cell. On the interiormost core of matter body, the interior soul essence is wrapped in interiormost core of super conscience of mental health. The mind carries, in writing, an account of the result oriented karma actions, as per the cosmic power of interior nature essence. The process of thought flows above the unconscious mind that touches the matter body of endless individual cells of living human body. The part of the formless nature essence in mind, which contains an account of karma actions, is called the enlightened mind or conscience of mental health. The effort to come to an end the flow of thoughts of millions of living cells in conscience of mental health is called spiritual union with yoga by Guru Patanjali. As long as the flow of thoughts of all the living cells continues and is not stopped, the mind does not get enlighten. It keeps on hovering in a state of lack of spiritual knowledge .It does not get true and complete knowledge.
