This is what Ramana Maharshi says

From ~~~ Who Am I ?.

8 : What is the nature of the mind?

What is called ‘mind’ is a wondrous power residing in the Self. It causes all thoughts to arise. Apart from thoughts, there is no such thing as mind. Therefore, thought is the nature of mind. Apart from thoughts, there is no independent entity called the world. In deep sleep there are no thoughts, and there is no world. In the states of waking and dream, there are thoughts, and there is a world also. Just as the spider emits the thread (of the web) out of itself and again withdraws it into itself, likewise the mind projects the world out of itself and again resolves it into itself. When the mind comes out of the Self, the world appears. Therefore, when the world appears (to be real), the Self does not appear; and when the Self appears (shines) the world does not appear. When one persistently inquires into the nature of the mind, the mind will end leaving the Self (as the residue). What is referred to as the Self is the Atman. The mind always exists only in dependence on something gross; it cannot stay alone. It is the mind that is called the subtle body or the soul (jiva).

However Yukteshwar had a different explanation. He called it something that wants to move outward anandatattva. He called the soul as something within ego / chit
See the holy science. There is a nice diagram

I call the mind as nothing but the pleasure principle.
Something that always craves happiness. It is foolishness. Why? It only knows happiness in this world. Or in sleep. Foolishly it does not want to find joy within the light of God. Or when it does it does not recognize it or rejects it.

It takes time. Even if a Guru gave you experience, your mind will reject it. I have given the nectar of religion in many places but there is an inherent stubbornness which prevents people from accepting

This is natural. But in time the mind adjusts itself. It will calmly go within. Not the rushes anxiety provoked insecurity of wanting to go within.
The mind will doubt.

Everyone who has reached a high level has taken several births. Buddha took 100 births it is said.

The longer the path the higher the achievement / glory
