Poigai alwar says “if a devotee wants to call the lord by a certain name, bhagavan accepts the same as his own. If a devotee wish to see the god, by a certain form, then the lord accepts the form as his own. Bhagavan stays inside our body as invisible and does good for us. Why? The lord shows his darsan for his devotees as divine idols. How? If we listen the holiness of idol worshipping, we can understand the meaning with detailed answer. Enjoy with divine pleasure!
