“If one could achieve success without the sanction of the Lord then no medical practitioner would fail to cure a patient. Despite the most advanced treatment of a suffering patient by the most up-to-date medical practitioner, there is death, and even in the most hopeless case, without medical treatment, a patient is cured astonishingly. Therefore the conclusion is that God's sanction is the immediate cause for all happenings, good or bad.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.14.9 Purport)
