From a letter written by Srila Prabhupada to his disciple, Guru das, on February 13, 1968:
I have received also one letter from Upendra today, and I am so glad he is released within 10 days. That was my expectation when he came to see me, that he couldn't be incarcerated for more than a week. This instance of suffering by a devotee should be carefully noted. As Upendra was in the beginning incarcerated for 3 months, it was reduced to one week; similarly, when a devotee is seen in trouble, it should be accepted as God's Mercy.
Just like Upendra's suffering for 3 months was destined by the law, but by the Mercy of God the suffering is reduced to one week only. So a devotee always accepts his distress as minimized by God's Mercy, although he would have to suffer many more times the suffering. Any one who accepts this philosophy of God's Mercy in suffering conditions, and still makes progress in Krishna Consciousness, it is said that he is sure to go back to Home, Back to Godhead.
