" The duty must be done, even if there is a little suffering involved. That is called tapasya, or austerity. Tapasya means that we must proceed with our business of Kṛṣṇa consciousness despite all the dangers and calamities of this world. This is called tapasya, or voluntary acceptance of the difficulties of life. "
