We Don't Worship Dolls - Prabhupada 0272
710811 - Lecture BS 5.37 - London
Just like in front of your door there is a mailbox. That mailbox, although it appears to be small box, but it is Post Office. It is not different from Post Office. The practical example is that you place your letters within the box and it goes thousands and thousand miles away. Therefore it is Post Office. Don't think that it is different from the Post Office.
Similarly, ānanda-cinmaya-rasa expansion—this Deity. When you are worshiping this Deity, exactly just like you are posting your letters in the mailbox, it is accepted by Kṛṣṇa. Don't think that you are worshiping some doll. No. As the Post Office kindly places a box before your house to facilitate your business, similarly Kṛṣṇa, goloka eva nivasati, He is living in the Goloka Vṛndāvana, but He expands Himself as Deity to accept your humble service."
