Bhagavad Gita 6.24

6.24 Abandoning without reserve all desires born of Sankalpa (thought and imagination) and completely restraining the whole group of the senses by the mind from all sides.

One should engage oneself in the practice of yoga with determination and faith and not be deviated from the path. One should abandon, without exception, all material desires born of mental speculation and thus control all the senses on all sides by the mind.
