If you spent one-tenth of the time you devoted to distractions like chasing women or making money to spiritual practice, you would be enlightened in a few years.
You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
God laughs on two occasions. He laughs when the physician says to the patient's mother, 'Don't be afraid, mother; I shall certainly cure your boy.' God laughs, saying to Himself, 'I am going to take his life, and this man says he will save it!' The physician thinks he is the master, forgetting that God is the Master. God laughs again when two brothers divide their land with a string, saying to each other, 'This side is mine and that side is yours.' He laughs and says to Himself, 'The whole universe belongs to Me, but they say they own this portion or that portion.'
God has revealed to me that only the Paramatman, whom the Vedas describe as the Pure Soul, is as immutable as Mount Sumeru, unattached, and beyond pain and pleasure. There is much confusion in this world of His maya. One can by no means say that 'this' will come after 'that' or 'this' will produce 'that'.
Too much study of the scriptures does more harm than good. The important thing is to know the essence of the scriptures. After that, what is the need of books? One should learn the essence and then dive deep in order to realize God.
The rishis of old attained the Knowledge of Brahman. One cannot have this so long as there is the slightest trace of worldliness. How hard the rishis laboured ! Early in the morning they would go away from the hermitage, and would spend the whole day in solitude, meditating on Brahman. At night they would return to the hermitage and eat a little fruit or roots. They kept their mind aloof from the objects of sight, hearing, touch, and other things of a worldly nature. Only thus did they realize Brahman as their own inner conciousness.
One cannot attain divine knowledge till one gets rid of pride. Water does not stay on the top of a mound; but into low land it flows in torrents from all sides.
The sun can give heat and light to the whole world, but he cannot do so when the clouds shut out his rays. Similarly as long as egotism veils the heart, God cannot shine upon it.
God can be realized through all paths. All religions are true. The important thing is to reach the roof. You can reach it by stone stairs or by wooden stairs or by bamboo steps or by a rope. You can also climb up by a bamboo pole.
