SB 4.13.28

It is indicated herein that if there is negligence on the part of the priest, the demigods do not accept their share in sacrifices. Similarly, in devotional service there are offenses known as sevā-aparādha. Those who are engaged in worshiping the Deity, Rādhā and Kṛṣṇa, in the temple, should avoid such offenses in service. The offenses in service are described in The Nectar of Devotion. If we simply make a show of offering services to the Deity but do not care for the sevā-aparādha, certainly the Rādhā-Kṛṣṇa Deity will not accept offerings from such nondevotees. Devotees engaged in temple worship should therefore not manufacture their own methods but should strictly follow the regulative principles of cleanliness, and then offerings will be accepted.
