To pay our respects, obeisance to the mighty creator of entire cosmos, people world over often worshipped God. By worshipping God we only trying to repay for services rendered by him absolutely free of all costs.
We every time consume free air, water and everything natural on mother earth and at times felt obligated to God, Brahman in Hinduism. None had seen God but we can feel his presence all the time in day-to-day activities of life.
True worship to God means serving entire mankind all the time and working like a trustee, a caretaker for whom everything all the time belonged to God Almighty! Unless we rendered service to mankind, true worship of God is not possible.
Furthermore as all human beings were children of God, in serving mankind we are only serving God.
Simply going to temples, churches and mosques and praying is not true worship of God. In Bhagavad Gita Lord Krishna specifically points out that all worship and prayers must be directly offered to Brahman and not its attributes, hordes of gods and goddesses that include even Lord Brahma, Lord Vishnu and Lord Shiva.
Ritual indulgence in worship is prohibited in Bhagavad Gita. The sermon of Bhagavad Gita by Lord Krishna is a spiritual treatise having nothing to do with religious aspect of life. Anything falling under religious practices (rituals) never leads mankind to God.
JRD Tata a perfect Karma Yogi rendered true worship to God all the time. JRD Tata never considered himself as owner of Tata Empire. JRD Tata firmly believed that all human beings were merely trustees as everything in cosmic system belonged to world of souls’ atmans, the spirit inside us. We were only an instrument in hands of God Almighty doing his bidding all the time.
JRD Tata knew nothing of Bhagavad Gita yet he practiced teachings of Bhagavad Gita in his life all the time.
