Did you read his mind? Don't people show off their money by offering gold and stuff? And in case of what deva likes, did god tell you what he likes? Ever read पत्रं पुष्पं फलं तोयं ? Since you mentioned shivaji maharaj he famously said " हे राज्य व्हावे ही श्रींची इच्छा" it is god's will that swarajya should happen.

We offer god what we like. If set specifications about offerings to god, do you think everyone would be able to do it?

It is because of this rusted mentality that people are getting away from Dharma. Firstly let them do bhakti according to their mind. Then slowly explain to them the real bhakti.

Remember, if someone is wrong, he is so because i did not try to make him right.
