Srimad Bhagavatam Canto 07, Chapter 01, Text 30

SB 7.1.30

kamad dvesad bhayat snehad
 yatha bhaktyesvare manah
avesya tad-agham hitva
 bahavas tad-gatim gatah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Many, many persons have attained liberation simply by thinking of Krsna with great attention and giving up sinful activities. This great attention may be due to lusty desires, inimical feelings, fear, affection or devotional service. I shall now explain how one receives Krsna’s mercy simply by concentrating one’s mind upon Him.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
As stated in Srimad-Bhagavatam (10.33.39):
 
vikriditam vraja-vadhubhir idam ca visnoh
 sraddhanvito ’nusrnuyad atha varnayed yah
bhaktim param bhagavati pratilabhya kamam
 hrd-rogam asv apahinoty acirena dhirah
 
If a bona fide listener hears of Krsna’s pastimes with the gopis, which seem to be lusty affairs, the lusty desires in his heart, which constitute the heart disease of the conditioned soul, will be vanquished, and he will become a most exalted devotee of the Lord. If one who hears of the gopis’ lusty behavior with Krsna becomes free from lusty desires, certainly the gopis who approached Krsna became free from all such desires. Similarly, Sisupala and others who were very much envious of Krsna and who constantly thought of Krsna became free from envy. Nanda Maharaja and mother Yasoda were fully absorbed in Krsna consciousness because of affection. When the mind is somehow or other fully absorbed in Krsna, the material part is very soon vanquished, and the spiritual part — attraction to Krsna — becomes manifest. This indirectly confirms that if one thinks of Krsna enviously, simply because of thinking of Krsna he becomes free from all sinful reactions and thus becomes a pure devotee. Examples of this are given in the following verse.
