 SB 4.29.79

atas tad apavadartham
 bhaja sarvatmana harim
pasyams tad-atmakam visvam
 sthity-utpatty-apyaya yatah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
You should always know that this cosmic manifestation is created, maintained and annihilated by the will of the Supreme Personality of Godhead. Consequently, everything within this cosmic manifestation is under the control of the Lord. To be enlightened by this perfect knowledge, one should always engage himself in the devotional service of the Lord.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Self-realization, understanding oneself as Brahman, or spirit soul, is very difficult in the material condition. However, if we accept the devotional service of the Lord, the Lord will gradually reveal Himself. In this way the progressive devotee will gradually realize his spiritual position. We cannot see anything in the darkness of night, not even our own selves, but when there is sunshine we can see not only the sun but everything within the world as well. Lord Krsna explains in the Seventh Chapter of the Bhagavad-gita (7.1):
 
mayy asakta-manah partha
 yogam yuñjan mad-asrayah
asamsayam samagram mam
 yatha jñasyasi tac chrnu
 
“Now hear, O son of Prtha [Arjuna], how by practicing yoga in full consciousness of Me, with mind attached to Me, you can know Me in full, free from doubt.”
 
When we engage ourselves in the devotional service of the Lord to become Krsna conscious, we understand not only Krsna but everything related to Krsna. In other words, through Krsna consciousness we can understand not only Krsna and the cosmic manifestation but also our constitutional position. In Krsna consciousness we can understand that the entire material creation is created by the Supreme Personality of Godhead, maintained by Him, annihilated by Him and absorbed in Him. We are also part and parcel of the Lord. Everything is under the control of the Lord, and therefore our only duty is to surrender unto the Supreme and engage in His transcendental loving service.
