Right discrimination is of two kinds analytical and synthetical. The first leads one from the phenomena to the Absolute Brahman, while by the second one knows how the Absolute Brahman appears as the universe.
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.
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.
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.
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.
It is true that God is even in the tiger, but we must not go and face the animal. So it is true that God dwells even in the most wicked, but it is not meet that we should associate with the wicked.
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.
The ordinary man says in his ignorance, "My religion is the sole religion, my religion is the best." But when his heart is illuminated by the true knowledge, he knows that beyond all the battles of sects and of sectaries presides the one, indivisible, eternal and omnipresent Benediction.
When you meditate, go into the solitude of a forest, or a quiet corner, and enter into the chamber of your heart. And always keep your power of discrimination awake.
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.
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 .
