Having kept both the hands together in the lap, performing the Padmâsana firmly, keeping the chin Fixed to the chest and contemplating on Him in the mind, by drawing the apâna-vâyû up (performing Mûla Bandha) and pushing down the air after inhaling it, joining thus the prâṇa and apâna in the navel, one gets the highest intelligence by awakening the śakti (kundalinî) thus. Note - When Apâna Vâyû is drawn gently up and after filling in the lungs with the air from outside, the prâṇa is forced down by and by so as to join both of them in the navel, they both enter then the Kundalinî and, reaching the Brahma randhra (the great hole), they make the mind calm. Then the mind can contemplate on the nature of the âtmana and can enjoy the highest bliss.
