I have seen many youtube videos and photos of Indian Muslims directly participating in Hindu religious activities and rituals by worshipping Hindu idols, etc. However, I never saw the opposite. I.e., I never saw a Hindu praying in a mosque, etc.

Is the similar observed in other secular countries (i.e., only the minority community participates in majority religions and not the other way around)?

Explain, why?

EDIT: The current answer mentions arranging Iftar parties by Hindus. This is charity work, the same as Sikh Langar. This is not directly participating in Islamic religious activities. It would have been mentionable if Hindus fasted during the month of Ramadan.
