This being the condition, breath is vitalizing. Naturally, therefore, the breath of a man in sound health must give health to another in his presence; the breath of a mastermind must vitalize the thought of another; and the breath of a spiritual person must illuminate those in his presence. By breath a spiritually-developed person can impart his physical energy, his thought-power and his spiritual influence to the others with whom he may come in contact. It is natural, no doubt, that if the one who wishes to impart has not sufficient power to impart he becomes broken if there is a greater demand on his power and if there is little left with him. Sufis, therefore, consider breathing connected with meditation much more important than anything else in the world, their food, sleep, or comfort.
