Srimad Bhagavatam Canto 07, Chapter 15, Text 62

SB 7.15.62

bhavadvaitam kriyadvaitam
 dravyadvaitam tathatmanah
vartayan svanubhutyeha
 trin svapnan dhunute munih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
After considering the oneness of existence, activity and paraphernalia and after realizing the self to be different from all actions and reactions, the mental speculator [muni], according to his own realization, gives up the three states of wakefulness, dreaming and sleep.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The three words bhavadvaita, kriyadvaita and dravyadvaita are explained in the following verses. However, one has to give up all the nonduality of philosophical life in the material world and come to the actual life of reality in the spiritual world in order to attain perfection.
