yatha hi skandha-sakhanam
evam aradhanam visnoh
sarvesam atmanas ca hi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When one pours water on the root of a tree, the trunk and branches of the tree are automatically pleased. Similarly, when one becomes a devotee of Lord Visnu, everyone is served, for the Lord is the Supersoul of everyone.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As stated in the Padma Purana:
visnor aradhanam param
tasmat parataram devi
“Of all types of worship, worship of Lord Visnu is best, and better than the worship of Lord Visnu is the worship of His devotee, the Vaisnava.” There are many demigods worshiped by people who are attached to material desires (kamais tais tair hrta jñanah prapadyante ’nya-devatah). Because people are embarrassed by so many material desires, they worship Lord Siva, Lord Brahma, the goddess Kali, Durga, Ganesa and Surya to achieve different results. However, one can achieve all these results simultaneously just by worshiping Lord Visnu. As stated elsewhere in the Bhagavatam (4.31.14):
yatha taror mula-nisecanena
pranopaharac ca yathendriyanam
tathaiva sarvarhanam acyutejya
“Just by pouring water on the root of a tree, one nourishes its trunk and all of its branches, fruits and flowers, and just by supplying food to the stomach, one satisfies all the limbs of the body. Similarly, by worshiping Lord Visnu one can satisfy everyone.” Krsna consciousness is not a sectarian religious movement. Rather, it is meant for all-embracing welfare activities for the world. One can enter this movement without discrimination in terms of caste, creed, religion or nationality. If one is trained to worship the Supreme Personality of Godhead, Krsna, who is the origin of visnu-tattva, one can become fully satisfied and perfect in all respects.
