Everything is within you.

A man who has forgotten where he left his things in the house cannot recover them by weeping even for a hundred years. But he will get them only if he thinks the matter over and finds out.
The Self is realized directly by Knowledge which destroys forgetfulness (ignorance), the root-cause of all misery, but it cannot be realized by any amount of hard work, though extended over several aeons (Yugas).

Bhagavan Sri Ramana Maharshi.
