Meditation, witnessing, silently sitting and looking at the mind, will be of much help. Not forcing, simply sitting and looking. Not doing much, just watching as one watches birds flying in the sky. Just lying down on the ground and watching, nothing to do, indifferent. Not your concern really, where they are going; they are going on their own.

Remember, thoughts are also just like birds: they are moving on their own. And sometimes it happens that people who are around you, their thoughts enter into your sky, your thoughts go on entering into their sky. That's why sometimes you feel that with some man suddenly you become sad; with some other man suddenly you feel an upsurge of energy and happiness and delight. Just looking at somebody, being near to him, something changes in your mood.
