3.37 The Lord said  The highly ravenous desire is born of the Guna Rajas originating from old subtle impressions. It has for its objects sound and other sense contacts. It is a foe to him who is practising Jnana Yoga, as he is joined with Prakrti constituted of the Gunas which rise and subside periodically. It attracts him towards the objects of the senses. It is this desire alone which, when hampered, develops into anger towards those persons who are the cause of such hindrance. It is a powerful cause of sin. It incites the aspirant to do harm to others. Know this, which is born of the Guna called Rajas, as the natural enemy of Jnana Yogins.
