Remember it always, The Bhagwad Gita already prescribed these four broad methods of worship:
1. Idolworshipping: Simple and sweet. Easy to decorate, imagine and connect with the PäräBrähmä. It promotes arts and literature.
2. Non-idolworshipping: These forms of worship don't require any stone or materialistic idols to connect with PäräBrähmä. It's also very easy to misinterpret.
3. Agnosticism: Here people are not concerned about PäräBrähmä as such but their refuting the existence of Brähmā is making them Hïnđūs.
4. Atheism: These people are fed up with the popular concept of PäräBrähmä because there's no point that they can see is favourable for them.
In Bhāgwäđ Gītā, Präbhü Śrī Kṛṣṇä lays down a very simple explanation of how all of the above ultimately lead to The PäräBrähmä.
