“As the Lord's desire is infallible because He is achyuta, similarly the desires of the devotees in the transcendental service of the Lord are also achyuta, infallible. This is very difficult, however, for the layman to understand without knowledge of the mystery of devotional service, as it is very difficult to know the potency of touchstone.” (Shrila Prabhupada, Shrimad Bhagavatam, 2.9.35 Purport)
