“One should be in spontaneous samadhi – that is, in one’s pristine state – in the midst of every environment.”
Later on Sri Bhagavan said: “Control of breath may be internal or external.
The antah pranayama (the internal breath-regulation) is as follows:
Naham chinta (I-am-not-the-body idea) is rechaka (exhalation).
Koham (who am I?) is puraka (inhalation).
Soham (I am He) is kumbhaka (retention of breath).
Doing thus, the breath becomes automatically controlled.
Bahih pranayama (external control) is for one not endowed with strength to control the mind. There is no way so sure as that; or a sadhu’s company. The external practice must be resorted to by a wise man if he does not enjoy a sadhu’s company. If in a sadhu’s company the sadhu provides the needed strength, though unseen by others, Pranayama need not be exactly as described in hatha Yoga.
If engaged in japa, dhyana, bhakti, etc., just a little control of breath will suffice to control the mind. The mind is the rider and the breath the horse. Pranayama is a check on the horse. By that check the rider is checked.
Pranayama may be done just a little. To watch the breath is one way of doing it. The mind abstracted from other activities is engaged in watching the breath. That controls the breath; and in its turn the mind is controlled.”
