When to make efforts and when to surrender...

Where and when to exert self-effort or puruShArtha and where and when to surrender, these are known to those who have had the direct experience of God.

Again, what is dharma and what is adharma is also known to such minds.

These depend on desh, kAl and paristhiti.

But to other minds these questions can be difficult to answer and create a lot of confusion. Then it is best to consult Guru or a guide and have faith in their instruction. If the ego in confusion tries to answer these questions without direct experience of God, it can come to completely incorrect conclusions.

Yet, everyone is doing their best according to their past karma. So one should criticize no one, but attend to one's puruShArtha, dharma and tyAga.

The Bhagavad GItA gives all the necessary guidance. SmRti. Yajna, dAna, tapa should never be given up. How it is practised may change according to desh, kAl and paristhiti.
