Make your meditation a continuous state of mind. A great worship is going on all the time, so nothing should be neglected or excluded from your constant meditative awareness.
Wisdom leads to unity, but ignorance to separation.
So long as God seems to be outside and far away, there is ignorance.
But when God is realised within, that is true knowledge.
Take the case of the infinite ocean. There is no limit to its water. Suppose a pot is immersed in it: there is water both inside and outside the pot. The jnani sees that both inside and outside there is nothing but Paramatman. Then what is this pot? It is 'I-consciousness'. Because of the pot the water appears to be divided into two parts; because of the pot you seem to perceive an inside and an outside. One feels that way as long as this pot of 'I' exists. When the 'I' disappears, what is remains. That cannot be described in words.
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.
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.
The magnetic needle always points to the north, and hence it is that sailing vessel does not lose her direction. So long as the heart of man is directed towards God, he cannot be lost in the ocean of worldliness.
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.
