I think many of us have heard of this statement

> भाग्यं फलति सर्वत्र, न च विद्या, न च पौरुषं or Bhagyam phalati sarvatra, na cha vidyaa, na cha paurusham

Which basically means that knowledge and masculine courage are useless as everything is based on your Bhaagya / Destiny. **Is this based on any sacred scripture?**

I have heard that you can easily change your long-term destiny by performing some austerities. In fact, even weak and destructive planets can be changed.

**Which view is correct according to different scriptures?**
