go to church
Normally, never.
Hindus go to Hindu Temples to pray.
Mandir
Some hindus do not do anything special for 13 days.
To prepare for Diwali, Hindus decorate their homes with colorful decorations, lights, and candles. They also dress in fancy clothes, go to church, and celebrate.
Mosques are for Muslims and Temples are for Hindus like Church for Christians.
sundays
The vast majority of Hindus engage in religious rituals on a daily basis.
A Mandir is a place of worship, i.e. a temple. It is a Hindi word and usually refers to a Hindu place of worship. The mandir houses the idols of the Hindu dieties. They are worshipped and prayers are offered.
Why not!!!!
To the best of my knowledge the Hindus and the Catholic Church have nothing whatsoever in common in the way of religious rituals or ceremonies. The Catholic Church's rituals and ceremonies are rooted in the ancient Hebrew religion, not in the East.
