Great question. 🙂 Since it appears that this question is being asked again in a different way, let us go a notch deeper.
The motivation is to get to know what is Ego, for Ego makes for a miserable existence. That is it. The Drama is about having ego and not having ego. About remembering and forgetting. About praise and defamation. Duality.
I have answered your question.
Where is that “I do” coming from? If there are roles as you understand it, Am “I” really doing something? Or instead “I “rather believe that “I” do, thus “free will”? Isn’t that the reason that ego complains about, because it doesn’t like predestination?
How are we going to be able to flow with the Drama if there is an “I” who has an agenda already?
Your question has already been approached here:
Please read it a couple of times and see that we are being trapped by words, by concepts when in fact our experience is totally different. That is why ask yourself, where is that “I” who needs motivation to “do” something?
One more thing, our understanding of these points will depend on our level of awareness alone. Some people do not know what ego is. They do not perceive it. They cannot understand it. It is in the Drama!
So what? Is that important? In 5000 years they will be them again… So what is the motivation for them to change? None. Because according to the Drama, they do not need to understand ego. They do not require that role.
Do not look for motivation. See inside yourself if you have it within to explore the self. Then, it will be “natural,” what you have to do. Forget about the words “predestination and free will,” just look at the self. If you understand gyan , your motivation is what is burning inside you. Listen to the heart.
