One should not think, 'My religion alone is the right path and other religions are false.' God can be realized by means of all paths. It is enough to have sincere yearning for God. Infinite are the paths and infinite are the opinions.
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.
The way of love is as true as the way of knowledge. All paths ultimately lead to the same Truth. But as long as God keeps the feeling of ego in us, it is easier to follow the path of love.
Through selfless work, love of God grows in the heart. Then through his grace one realize him in course of time. God can be seen. One can talk to him as I am talking to you.
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.'
As the shell, the pith and the kernel of the fruit are all produced form one parent seed of the tree, so from the one Lord is produced the whole of creation, animate and inanimate, spiritual and material.
Meditate upon the Knowledge and Bliss Eternal , and you will also have bliss. The Bliss indeed is eternal, only it is covered and obscured by ignorance. The less your attachment is towards the senses, the more will be your love towards God .
There are three kinds of love;
unselfish, mutual, and selfish.
The unselfish love is of the highest kind;
The lover only minds the welfare of the beloved and does not care for his own sufferings.
In mutual love the lover not only wants the happiness of his beloved;
but has an eye towards his own happiness also. It is middling.
The selfish love is the lowest. It only looks towards its own happiness,
no matter whether the beloved suffers weal or woe.
Sunlight is one and the same wherever it falls; but only a bright surface like that of water, or of a mirror reflects it fully. So is the light Divine. It falls equally and impartially on all hearts, but the pure and pious hearts of holy men receive and reflect that light well.
