The second you say, "I've left the old me. Now I've found my true self" is the second you start believing in a new self-image. In other words, it's the second you start a new cycle of deceiving yourself.
We go on defining and redefining ourselves our entire life. putting on mask after mask. not realizing who/what exactly is trying on all these masks. not realizing who/what is playing these roles in this play of life.
Think about who you were 10 years ago. Really think back and picture the person you thought you were back then.
Now think back 5 years ago. When you laughed embarrassingly at the 'you' from 10 years ago. If I had asked you 5 years ago "who are you?" you would've said "I have grown a lot, and now I've found myself".
But look at how much you've changed now from 5 years ago. If I asked you now, you would say the same thing. That you were young and a bit foolish 5 years ago but now you've found yourself and that this is the real you.
The wise realize that self-images change, beliefs change, and personalities change--and so they drop these concepts completely. If you truly see this, if you know this, you will realize that what you are cannot possibly be defined by a personality.
There is no "real you" that you unlock when you improve yourself to the right degree of confidence, skills and personality traits. So I'll save you a lifetime of searching for, and trying to become this perfect self. It doesn't exist.
So then what is the truth of who/what you are? If not a personality, then what exactly are you? This becomes obvious as you empty yourself. Empty of any self-image, empty of beliefs, empty mind in each moment.
Be empty and observe, with this question silently in your heart, as you move thru each moment of life. If your search is true, you will find true inner peace.
Of course we have some limited choice. For example you can choose to read the rest of this caption or to just keep scrolling. But in the bigger picture, we don't really have control over other people or what happens in our life. If we did, then our lives would be "perfect" and we would only ever experience love and positivity. But obviously this is not the case since we are constantly experiencing things that are painful/undesirable etc. Because we don't control life. Matter of fact, we don't even have control over our own thoughts. Do you get to control what you're going to think about throughout your day? No, thoughts just randomly pop into your head.
Those who observe closely, will see that Life takes care of life. An incredible inner peace comes from this. I wish this peace upon you.
