Sense-perceptions can only be indirect knowledge, and not direct knowledge. Only one's own awareness is direct knowledge.
Ramana MaharshiTill you reach the state of jnana and thus wake out of maya you must do social service by relieving suffering whenever you see it. But even then you must do it without ahankara, i.e., without the sense of 'I am the doer', but with the feeling 'I am the Lord's tool'.
Ramana MaharshiRealisation is not acquisition of anything new nor is it a new faculty. It is only removal of all camouflage
Ramana MaharshiWhy should we... constantly worry ourselves... as to what should be done and how, and what should not be done and how not? We know that the train carries all loads, so after getting on it why should we carry our small luggage on our head to our discomfort, instead of putting it down in the train and feeling at ease?
