Illness is caused by the malnutrition of the mind than of 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. That is the 'Vitamin G'.  That is the medicine. Regulated life and habits are two-thirds of the treatment, while the medicine is only one-third.

- Divine Discourse, April 28, 1975 .

Do not reduce spiritual effort to a mere daily routine. - Baba
