How can you move Within?

"The Upanishads are trying to throw you to yourself. Forget the object of worship... just move within. And how can you move within? It is easy to forget the object of worship, but it is difficult to move within because there are objects still in the mind which go on clinging around you. Whenever you close your eyes, there is a world of imagination around you: dreams go on floating, images come up, thoughts move in a procession. Again you are in a world. The world of things is no more there, but the world of thoughts is there. Unless this world of thoughts also ceases, you cannot know the worshipper.
And how will it cease if you go on cooperating with it, go on creating it? You cannot destroy the world of things because you never created it. Remember, – you cannot destroy the world of things. How can you destroy the hills, the earth, the moon, the stars? You cannot destroy them because you never created them! But you can destroy the world of thoughts because you are the sole creator there. No one else has helped you. You alone have done the whole work.
Thoughts exist because you cooperate with them. Do not cooperate – this is the only technique. Be indifferent. Just look at them without loving them, without hating them, without condemning them, without appreciating them, without saying they are good, without saying they are bad. Do not say anything; do not take any attitude. Just be indifferent, an onlooker…"
