When the mind of a person is unattached to the ups and downs of life, but is able to maintain equanimity under all circumstances, then even physical health can be assured. The mental firmament must be like the sky, which bears no mark of the passage through it of birds or planes or clouds. Illness is caused more by malnutrition of the mind than of the body. Doctors speak of vitamin deficiency; I will call it the deficiency of Vitamin G, and I will recommend the repetition of the Name of God, with accompanying contemplation of the glory and grace of God. This Vitamin G is the medicine that is needed. Regulated life and habits are two-thirds of the treatment, while the medicine is just one-third. You must reveal the divine qualities of love, humility, detachment and contentment. Else, you could become worse than a beast and in fact more deadly.

- Divine Discourse, Sep 27, 1965.
