Control the Mind
To control thinking is not called as control of mind. It is difficult to control the mind when one is in ignorance. But by knowledge of Self-Realization, one can remain separate from mind.
The mind is a projector and the thoughts that arise in the mind are like a film which plays continuously. Param Pujya Dadashri has discovered the inner workings of the mind and has explained it in an understandable manner.
When your mind is overcrowded with racing thoughts you try to find an escape using diversions or different activities. However, these are all temporary solutions. Once these activities have ended, countless thoughts continue to buzz around like a fly.
Analyze the thoughts that arise in your mind. Some thoughts are beneficial while others are not. Filter out the thoughts that are not beneficial. Walk only according to the thoughts that take you towards your goal. Eventually you will obtain the reins of the mind and thus be able to still the mind. This still mind will result in a Healthy minds. Otherwise you will drown in the ocean of thoughts that are not beneficial to you and the mind will control you.
After attaining Self Realization, you can easily control mind.
