Sri Swami Sivananda Saraswati detailly explains that it is possible inside deep Sadhana Dharana states to forget the thirst and the hunger. Kundalini Yog practices, Kriya Yog, certain Mudras, and Bandhanas, are the ways.
The necessity of a Guru comes as a layer to educate your body to go into this process. Contemporary main-stream do acknowledge SadhGuRu and Isha Foundation also for the teaching and explaining of similar practices. Then is difficult to do that with the mind focused on the daily life needs. It is a path and a very personal one.

The Purushas When we forget Pashu wills. Those Pashu instincts are into the ignorance Aavidya of when you are born and Jeevaaatma forget the Purusha realization of the past births. Because of the trauma of birth, all is forgot and the attachment cycle again begins.
