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.
These people are like ... a frog living in a well, who has never seen the outside world. He knows only his well, so he will not believe that there is such a thing as the world. Likewise, people talk so much about the world because they have not known the joy of 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.
Brahman is beyond mind and speech, beyond concentration and meditation, beyond the knower, the known and knowledge, beyond even the conception of the real and unreal. In short, It is beyond all relativity.
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.
More are the names of God and infinite are the forms through which He may be approached. In whatever name and form you worship Him, through them you will realise Him.
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
With sincerity and earnestness one can realize God through all religions. The Vaishnavas will realize God, and so will the Saktas, the Vedantists, and the Brahmos. The Mussalmans and Christians will realize Him too. All will certainly realize God if they are earnest and sincere.
God reveals Himself to a devotee who feels drawn to Him by the combined force of these three attractions: the attraction of worldly possessions for the worldly man, the child's attraction for its mother, and the husband's attraction for the chaste wife. If one feels drawn to Him by the combined force of these three attractions, then through it one can attain Him.
The waves belong to the Ganges, not the Ganges to the waves. A man cannot realize God unless he gets rid of all such egotistic ideas as "I am such an important man" or "I am so and so". Level the mound of "I" to the ground by dissolving it with tears of devotion.
