Srimad Bhagavatam Canto 09, Chapter 09, Text 12

SB 9.9.12

yaj-jala-sparsa-matrena
 brahma-danda-hata api
sagaratmaja divam jagmuh
 kevalam deha-bhasmabhih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Because the sons of Sagara Maharaja had offended a great personality, the heat of their bodies had increased, and they were burnt to ashes. But simply by being sprinkled with water from the Ganges, all of them became eligible to go to the heavenly planets. What then is to be said of those who use the water of mother Ganges to worship her?
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Mother Ganges is worshiped by the water of the Ganges: a devotee takes a little water from the Ganges and offers it back to the Ganges. When the devotee takes the water, mother Ganges does not lose anything, and when the water is offered back, mother Ganges does not increase, but in this way the worshiper of the Ganges is benefited. Similarly, a devotee of the Lord offers the Lord patram puspam phalam toyam — a leaf, flower, fruit or water — in great devotion, but everything, including the leaf, flower, fruit and water, belongs to the Lord, and therefore there is nothing to renounce or to accept. One must simply take advantage of the bhakti process because by following this process one does not lose anything but one gains the favor of the Supreme Person.
