Bhagavad Gita Chapter 8
Powerful Cognition
Anyone who is in a path to attain Brahman is a Brahmachari
sarva-dvārāṇi saṃyamya mano hṛdi nirudhya ca mūrdhny ādhāyātmanaḥ prāṇam āsthito yogadhāraṇām
Closing all the doors of the senses and fixing the mind on the heart and the life air at the top of the head, one establishes himself in yoga.
Powerful Cognition
Yoga means the continuous process of uniting our mind, body and soul.
om ity ekākṣaraṃ brahma vyāharan mām anusmaranyaḥ prayāti tyajandehaṃ sa yāti paramāṃ gatiṃ
Centered in this yoga practice and vibrating the sacred OM, the supreme combination of letters, if one dwells in the Supreme and quits his body, he certainly achieves the supreme destination.
