Srimad Bhagavatam Canto 03, Chapter 20, Text 53

SB 3.20.53

tebhyas caikaikasah svasya
 dehasyamsam adad ajah
yat tat samadhi-yogarddhi-
 tapo-vidya-viraktimat
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
To each one of these sons the unborn creator of the universe gave a part of his own body, which was characterized by deep meditation, mental concentration, supernatural power, austerity, adoration and renunciation.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The word viraktimat in this verse means “possessed of the qualification of renunciation.” Spiritual realization cannot be attained by materialistic persons. For those who are addicted to sense enjoyment, spiritual realization is not possible. In Bhagavad-gita it is stated that those who are too attached to seeking material possessions and material enjoyment cannot reach yoga-samadhi, absorption in Krsna consciousness. Propaganda that one can enjoy this life materially and at the same time spiritually advance is simply bogus. The principles of renunciation are four: (1) to avoid illicit sex life, (2) to avoid meat-eating, (3) to avoid intoxication and (4) to avoid gambling. These four principles are called tapasya, or austerity. To absorb the mind in the Supreme in Krsna consciousness is the process of spiritual realization.
 
Thus end the Bhaktivedanta purports of the Third Canto, Twentieth Chapter, of the Srimad-Bhagavatam, entitled “Conversation Between Maitreya and Vidura.”
