Teachings of Queen Kunti devi :Chapter 6: The Master of the Senses

The Krsna consciousness movement, however, is meant for one who is no longer jealous or envious. By becoming free from jealousy and envy, one becomes a perfect person. Dharmah projjhita-kaitavo 'tra paramo nirmatsaranam satam (SB1.1.2). Those who are jealous and envious are within this material world, and those who are not are in the spiritual world. Therefore, we can test ourselves.
