Jayapataka Swami: We can ask the Deities forgiveness by prayer. The Deity is a person and the Deity can hear you praying. Once Srila Prabhupada asked the pujari, is the Deity happy? And the pujari was bewildered! And Srila Prabhupada said the pujari should know! So you should know if your Deity is satisfied or not, if you feel that your Deity Is not satisfied then maybe the Deity is not satisfied! So one thing is that, Home Deities Krsna is very pleased if you offer flowers. You can also offer Deities things that the Deity likes. The Deity will also be pleased.
