No one can cause mental pain to you. It is you - in reaction to something that happens around you.

When you are truly meditative, there is no time and space for you. Time and space are consequences of the mind.

You cannot suffer the past or future because they do not exist. What you are suffering is your memory and your imagination.

To be able to sit still, working only on your body is not enough. You also have to settle your mind, emotions, and energy.

If you do not know how to use it, the mind will use you and consume you.
