再生者应当无伪无诈、以奉爱之心献上相应供具来礼拜我——他应礼敬的主、亦为自师之形：或在圣像中，或在地上，或在火中，或在日轮中，或在水中，或在自心之中。
FAQs
This verse says worship may be offered to Kṛṣṇa not only in the Deity, but also on a sanctified altar, in fire, in the sun, in water, and within the heart—provided it is done with devotion and sincerity.
Kṛṣṇa teaches that genuine worship includes honoring one’s own guru, because the guru connects the disciple to proper bhakti practice and to Kṛṣṇa’s presence through authentic instruction and example.
Worship with honest intent: offer simple items and prayers, remember Kṛṣṇa in the heart, and serve and respect your guru/teachers—keeping devotion steady rather than showy or deceitful.
