What is a lie? Something which keeps changing is called a lie. If you said something yesterday, and today you say something else, then that is called a lie.
Now what is truth? Truth is that which is unaffected by time. Something which remains constant and unchanging through the three phases of time (past, present and future) is what is truth.
If you look around and see, everything is changing. The way you were yesterday, or ten years back, you are not the same today. In a year’s time, every cell in our body changes.
So, when I say ‘Everything is a lie’, it means everything is changing.
Now, when you understand that everything is changing, then there must be some reference point which doesn't change, through which you can know that everything is changing. And what is that reference point? That reference point is you.
If everything in you changes, then how can you say ‘I have changed’? If everything in you changes then you have become another person itself. So, you need some reference point for change to be observed, otherwise you can't even know change. There is something in you that is not changing, but what is this that is not changing is not very clear.
We usually say, ‘I went to this school 20 years back’, or, ‘I did this job 25 years back’, but who was that person? Even if you look at a picture of you taken around 20 years back, you will not find much resemblance. Your body, mind, intellect, thoughts, feelings, everything has changed. But certainly, there is something which has not changed because of which you can notice this change. That is why I say, first identify the changes that are happening within you. Once you identify these changes, then slowly you will be able to identify that what is not changing. And once you identify that which is not changing, then you will realize ‘This is what I am, this is what I have been searching for.’
