“ Just as a lamp in a windless place does not flicker, so the disciplined mind of a yogi remains steady in meditation ”
Source: Bhagavad Gita 6:19
Whenever and wherever the restless and unsteady mind wanders, one should bring it back and continually focus it on the self
When a man completely relinquishes all desires of the mind and is entirely contented in the self, by the self, he is then considered to be settled in wisdom
Undoubtedly the mind is fickle and unruly; but by yoga practice and by dispassion, the mind may nevertheless be controlled.
Verily, nothing else in this world is as sanctifying as wisdom. In due course of time, the devotee who is successful in yoga will spontaneously realize this within his Self.
If you stop identifying with things that you are not, your mind will become still. That's all it takes to meditate
