Manage of the sense organ for prana Yoga

Each of his five organs of perceptions and the five organs of external activities will now be controlled according to the divine disciplines. The activities of vision, hearing, smelling and tasting will be processed as per the directions of the soul. The mouth will not eat or say anything that is not worth the austere discipline. The genitals will not be misused for mere carnal pleasure; instead, these organs will be involved in sexual activities only when the reproduction of the offspring becomes necessary to fulfill the need of some noble purpose. The limbs would not indulge in any activity that goes against the altruist duties of a responsible person. The thoughts and emotions would always be inspired by the grace of God…
The mind will not allow any thought, which is away from virtuous in ideals; the intellect will not take any unfair, selfish, hasty, superficial or immature decision. The heart (emotional core) will not generate worldly ambitions or desires below the dignity of human being as a beloved child of thee.
The meditation and contemplation phases attached with the Pranayama of soaham are most important parts of this Sadhana. The Sadhaka's Sraddha and Viswasa should be so intense that these will not become mere mental exercises or entertaining activities; rather, these would 'shake' and 'stir' the entire personality. The positive effects of proper performance of these parts of the Soaham Sadhana would certainly be reflected in the Sadhaka's behavior and actions in daily life… The Sadhaka living in the same physical body would then become a divine being instead of remaining an ordinary mortal being or a social and intelligent animal.
The Soaham Pranayama is an excellent auto-suggestive experiment of psychology. After making an attempt to exhale all the weaknesses and sins with each breath, the Sadhaka indeed feels extremely relaxed and gets peace of mind. The feeling of receiving the Mahaprana with a breath increases his inner strength and deepens his Sraddha and self-confidence, which in turn becomes the motive force for the ascetic control of his body and mind and the source for his psychological and spiritual enlightenment. The inherent principle of Soaham gets inscribed in the inner self of the Sadhaka as his Sraddha deepens. This successively takes his life to the levels of that of the great personalities, sages and angels……
As stated earlier, ordinary Pranayamas offer the benefits of increasing the vital energy and mental creativity. The higher level Pranayamas are associated with meditation and willpower and thus result in - enhancing the internal motive force, spiritually refinancing the mental and emotional status and awakening some extraordinary potential. The Soaham Sadhana is a Pranayama of supreme level as it also involves Sraddha and Samkalpa and therefore gives rise to the 'string' of the reservoir of the individual consciousness and leads to 'merging' the latter in the ocean of divine consciousness.
The supernatural effects of Soaham are also highest among those of the other spiritual experiments of Pranayamas. Ten major and fifty-four minor - total sixty-four Pranayamas are described as the Sadhanas of Prana Yoga. Of these, the Soaham is supposed to be paramount. The penetration and awakening of the sat chakras becomes possible by this Sadhana.
When the (Mahapranaa is 'inhaled' through a breath during the Soaham Sadhana it first reaches the ajna chakra and gets divided into two components - one in the form of divine emotional charge and the other as vital energy. The first one reaches the heart - the emotional core and from there flows towards the different nuclei of conscious perception inside the body. It illuminates every corner of the inner body with the eternal glow of sat (absolute truth) and removes the ASAT (the darkness of ignorance and falsehood). The sublime currents of Prana reach the backside of the brain contain the flow of the Brahm Nadi.
