yad brahmani pare saksat
kriyadvaitam tad ucyate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear Yudhisthira [Partha], when all the activities one performs with his mind, words and body are dedicated directly to the service of the Supreme Personality of Godhead, one reaches oneness of activities, called kriyadvaita.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Krsna consciousness movement is teaching people how to come to the stage of dedicating everything to the service of the Supreme Personality of Godhead. Krsna says in Bhagavad-gita (9.27):
yat karosi yad asnasi
yaj juhosi dadasi yat
yat tapasyasi kaunteya
tat kurusva mad-arpanam
“O son of Kunti, all that you do, all that you eat, all that you offer and give away, as well as all austerities that you may perform, should be done as an offering unto Me.” If whatever we do, whatever we eat, whatever we think and whatever we plan is for the advancement of the Krsna consciousness movement, this is oneness. There is no difference between chanting for Krsna consciousness and working for Krsna consciousness. On the transcendental platform, they are one. But we must be guided by the spiritual master about this oneness; we should not manufacture our own oneness.
