Sri Swami Purohit belongs to the same spiritual tradition as Paramahansa Yogananda, the Giri Tradition.

In his book, Autobiography of a Yogi, Paramahansa Yogananda describes the science of Kriya Yoga this way:

“The Sanskrit root of Kriya is kri, ‘do’, ‘act’ ‘react’; We find the same root in the word karma, the natural principle of cause and effect. Thus, KriyaYoga means ‘union (yoga) with the infinite through a certain action or ritual’. The yogi who faithfully follows this technique is gradually freed from his karma, that is, from the just chain of balances between causes and effects.[…]

Kriya Yoga is a simple psychophysiological method by which human blood is freed from carbon dioxide and receives an additional amount of oxygen. The atoms of this additional oxygen are transmuted into vital energy, which rejuvenates the brain and spinal cord centers. By suspending the accumulation of venous blood, the yogi becomes able to slow down or prevent the wear and tear of tissues. The experienced yogi transmutes his cells into pure energy. Elijah, Jesus, Kabir and other prophets were masters in the use of Kriya, or a similar technique, by means of which they caused their bodies to materialize and dematerialize at will.

Kriya is an ancient science. Lahiri Mahasaya received it from his great guru, Babaji, who rediscovered and clarified it after it was lost in the Ancient Ages.[…] Babaji told Lahiri Mahasaya:

‘The Kriya Yoga that I am offering to the world through you, in this nineteenth century, is a resurrection of the same science that Krishna gave to Arjuna thousands of years ago, which was later known by Patanjali, Christ, Saint John, Saint Paul and other disciples.’”

The practice of Kriya Yoga requires that the body, mind and emotional capacity be strong. Therefore, the course has been divided into 3 different modules, each lasting 6 months.
