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.
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.
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.
If you feel proud, let it be in the thought that you are the servant of God, the son of God. Great men have the nature of a child. They are always a child before Him; so they are free from pride. All their strength is of God and not their own. It belongs to Him and comes from Him.
