2.2. The Bhagavat said O Arjuna ! At a critical moment, whence did this sinful act come to you which is practised by men of ignoble (low) birth and which is leading to the hell and is inglorious ?
2.2 Kutah etc. To commence with, the Bhagavat exhorts Arjuna just by following the worldly (common) practice; but, in due course, He will impart knowledge. Hence He says practised by men of low birth. Uttering words of ruke such as unmanliness etc., the Bhagavat causes [Arjuna] to know that he misconceives demerit as meritorious :
Sri Bhagavaan Uvaacha: Kutastwaa kashmalam idam vishame samupasthitam; Anaaryajushtam aswargyam akeertikaram arjuna.
