"Don't be implicated in the ugra-karma. Modern civilization is implicated in ugra-karma—vast machinery, everything complicated: the government complicated, the society complicated, economics rule complicated, foreign exchange complicated. Everything has become complicated.
So Narottama dāsa Ṭhākura has sung very nice song: sat-saṅga chāri kainu asate vilās, ei kāraṇe lāgila more karma bandha-phāṅsa. Because we have given up Kṛṣṇa consciousness, therefore we have been entangled in the different varieties of material activities. Now we have to simplify it. The Kṛṣṇa consciousness movement is to simplify, to save the valuable life, to save the time of valuable life. This human form of life is very valuable. Bahūnāṁ janmanām ante (BG 7.19). After many, many births we have got this important life. So we have to save our time to utilize it for Kṛṣṇa consciousness."
