“Further, he also added long ago,
the idea of Bhāvana in the practice of Prāṇāyāma.
Long, long ago, he said, the breathing,
inhalation, exhalation and retentions
have some sort of relationship with the highest force,
Inhalation is like an inspiration from God himself.
Retention is some sort of meditation, because you are with Him.
Exhalation is some sort of movement towards God,
and retention after exhale is like a surrender to God.”
