Good question!

You don't really aim for freedom - it simply happens as a result of being in a state of yoga and unity.

So, all you have to do is keep practizing...

This state of unity that you experience is like a spiritual muscle you build over time.

All the "experiences" like freedom, oneness, wisdom, etc are simply side effects from being in that state and connecting with the yoga stream

Makes sense right?

Now, yes... There is still something you can do practicaly:

Let go of what you know holds you back!

These can be mind sets, limiting beliefs, materials assets, action lines, etc.

Refocus your energy on what REALLY matters and let go of what you no longer need
