Sense-perceptions can only be indirect knowledge, and not direct knowledge. Only one's own awareness is direct knowledge.
Ramana MaharshiEvery living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.
Ramana MaharshiThe man who has the sense of the body being himself cannot possibly worship God as formless; whatever worship he makes will be worship in form alone, not otherwise.
Ramana MaharshiWillpower should be understood to be the strength of the mind, which makes it capable of meeting success or failure with equanimity. It is not synonymous with certain success. Why should one's attempts always be attended by success? Success breeds arrogance and man's spiritual progress is thus arrested. Failure, on the other hand, is beneficial, inasmuch as it opens his eyes to his limitations and prepares him to surrender himself. Self surrender is synonymous with eternal happiness.
Ramana MaharshiWe see only the script and not the paper on which the script is written. The paper is there, whether the script is on it or not. To those who look upon the script as real, you have to say that it is unreal - an illusion - since it rests upon the paper. The wise person looks upon both paper and script as one.
