Bring Bhakti and lay it here and take from here spiritual strength! The more such business is done, the more pleased am I. (SSS Vol.1)

Spiritual strength will be less in one, more in another, in proportion to the efforts of each, now and in the past. (SSS Vol.3)

Vows, vigils, fasts, etc. along with all kinds of voluntarily imposed or involuntarily suffered hardships are to be looked upon as promoting spiritual strength, not as weakening physical stamina. They dig around the roots and make the plant grow fast. They clip the wayward twigs and make the tree tall and truly trim. (SSS Vol. 6)

At this critical hour in the history of the world, when the demonic forces of fear and anxiety, injustice and inequity are raging in wild fury, it is the duty of every human being to be equipped with spiritual strength, so that he may not be overwhelmed by the storm. This is an urgent and essential task, and I must say that the women of India have a contribution to make, a service to render, a role to play. They must bring God into the hearts of the child and help it to keep Him there. For, faith in God is the tonic that man needs to get back health and happiness. (SSS Vol. 10)
