Guest: What is the purpose of the Deity worship?
Madhudviṣa: What is the purpose of Deity worship?
Prabhupāda: Deity means Kṛṣṇa's Deity. Kṛṣṇa and Kṛṣṇa's Deity is not different. The whole idea, spiritual knowledge, means to understand God. So vedaiś ca sarvair aham eva vedyam (BG 15.15). That is the purpose of Vedic knowledge. So just to favor you... You cannot see now God. So Kṛṣṇa has come in Deity form to accept your service. And we have to render service. Not that it is a doll or stone, no. He is Kṛṣṇa. Because you cannot see at the present moment except stone and wood, He has accepted this form like stone and wood so that you can see and render service. This is the purpose of Deity worship.
