So long as the bee is outside the petals of the lily, and has not tasted the sweetness of its honey, it hovers around the flower emitting the buzzing sound; but when it is inside the flower, it noiselessly drinks the nectar. So long as a man quarrels and disputes about doctrines and dogmas, he has not tasted the nectar of true faith; when he has tasted it, he becomes quiet and full of peace.
You must know that there are different tastes. There are also different powers of digestion... different temperaments... differences in the capacity to comprehend.
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.
As a toy fruit or a toy elephant reminds one of the real fruit and the living animal, so do the images that are worshipped remind one of the God who is formless and eternal.
Who may be called a paramahamsa? He who, like a swan, can take the milk from a mixture of milk and water, leaving aside the water. He who, like an ant, can take the sugar from a mixture of sugar and sand, leaving aside the sand.
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.
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.
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.
