HINDUISM : ? ON BHAGAVAD GITA : Which are that 4 things that GOD accept of devotee?

Tushar, you should know that, Bhagwat Gita is guiding principal to human to do its work with good spirit without caring for near and dear ones. It is not a religious book of Hindus.“India is a country of religious diversity and religious tolerance”, this is a fact. This is established by custom, & tradition, further supported by law. Preamble to the Constitution of India proclaimed India a "sovereign socialist secular democratic republic. Tolerance in Indian reference, some may not agree. But, fact is fact. There are number or religions in the world, almost all of them are in India. Actually, there are more. The off shoots of the Hindu religion and their sub branches, have not found place in the official list. So many religious groups, different practice and rituals, totally opposite, people are living peacefully until unless instigated by religious ‘fanatics’ of the country and from other land. There are countries having only one religion, people do not live in that harmony in name of religion. Indians accept and respect others religion. It retains a secular outlook.
