The prana goes out with sound вЂњhamвЂќ and goes in with the word вЂњsaвЂќ, and all beings naturally chant the mantra вЂњHamsa, HamsaвЂќ (while exhaling and inhaling). The great Maha Yoga, which is one, has been divided in to four and named as above. The four steps for this are Mantra Yoga, Laya Yoga, Hatha Yoga and Raja Yoga. Mind would get concentrated on the ever flowing bliss. The nectar will start flowing from the place of the moon. Without Pooraka and Rechaka, the Prana would stand in Kumbhaka for a very long time. If we sit in an asana and continuously practice, the bindu will cease from going down. If one continuously meditates on Parameshwara, he would become an expert in yoga and the Parameshwara would appear before him. After sitting in either Padmasana (lotus position) or any other Asana, and after concentrating the sight to the tip of the nose and after controlling both the hands and legs, meditate on the letter вЂOmвЂ™ with a concentrated mind. So I am teaching you this Yoga Shika (head of all yogas). There is no other option to get victory over Prana except Yoga and there are no methods except those shown by Siddhas. So the only way to win over this mind is through victory over Prana. Enquiries and researches do not affect the tie of this mind. Like a rope ties a bird, the minds of all living beings are tied. So the one who aims at salvation, should learn Jnana and Yoga together. How can Jnana without Yoga lead to salvation? It is also true that Yoga alone without Jnana will not lead to salvation. To attain occult powers, that alone will not suffice. Some people say that the only way out is Jnana (knowledge). вЂњAll the living beings are surrounded by the net of illusion, Oh God, Parameshwara, Oh God of Gods, How will they attain salvation? Be kind enough to tell.вЂќ Asked Lord Brahma to Lord Parameshwara and he replied as follows: 1.1 Let there be Peace in the forces that act on me ! May we not mutually dispute (or may we not hate any). May we work conjointly with great energy, Om ! May He protect us both together may He nourish us both together
