Shakti (doing/action) and Buddhi (knowing)

You may have heard of a prayer called, Serenity Prayer:

God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.

There is a tantra technique that Nithyananda explains in this video: Practising Living Enlightenment (about 33 min into this).

Nithyananda says in order to be enlightened, you need to have shakti (doing/action) to change what you can change and buddhi (knowing) to know and accept what you can't change. When you have this, there is no conflict. Living enlightenment is finally living a (internal) conflict free life.

So how do you know, what can be changed and what needs to be accepted. If in your sleep state, you are restless, many dreams, you feel stressed out, then there is something happening in your waking state that needs your shakti, your action to change. Like get organized or get your chores that you have been putting off for awhile, completed.

If you feel restless and stressed out in your waking state, then you need to apply buddhi (knowing) to your life.. look into your life and see there is something you are not accepting, something that "is" but you are not ready to accept "what is". Like your partner does not listen to you or your partner has moved on, but you cannot let go, or your parents don't help you, many of the other mind stories that keep us bound to suffering.

So in the waking state if you feel stressed out, you need to apply your buddhi (knowing) to accept things as they are. If you are restless in your sleep state, you need to apply shakti (doing) in your waking state to change things that can be changed.
