Anartha means... Anartha means that creates my miseries. Material activities will continue to increase my misery. And if you adopt spiritual life, then your material miseries will be gradually decreased, and practically it will be nil. And when we are actually free from material affinity, then your real spiritual life begins.
-Lecture on Bhagavad-Gita 2.58-59 -- New York, April 27, 1966

पाञ्चजन्यं हृषीकेशो देवदत्तं धनञ्जयः ।
पौण्ड्रं दध्मौ महाशङ्खं भीमकर्मा वृकोदरः ॥ १५ ॥
Lord Kṛṣṇa blew His conchshell, called Pāñcajanya; Arjuna blew his, the Devadatta; and Bhīma, the voracious eater and performer of herculean tasks, blew his terrific conchshell, called Pauṇḍra.
