The mind cannot dwell on God if it is immersed day and night in worldliness, in worldly duties and responsibilities; it is most necessary to go into solitude now and then and think of God.
To meditate, you should withdraw within yourself or retire to a secluded corner or to the forest. And you should always discriminate between the Real and the unreal. God alone is real, the Eternal Substance; all else is unreal, that is, impermanent. By discriminating thus, one should shake off impermanent objects from the mind.
(One) should practise discrimination and pray to God, 'Give me faith and devotion.' Once a person has faith he has achieved everything. There is nothing greater than faith.
God cannot remain unmoved if you have Raga-Bhakti, that is, love of God with passionate attachment to Him. Do you know how fond God is of His devotees' love? It is like the cow's fondness for fodder mixed with oil-cake. The cow gobbles it down greedily.
Do all your duties, but keep your mind on God. Live with all - with wife and children, father and mother - and serve them. Treat them as if they were very dear to you, but know in your heart of hearts that they do not belong to you.
When, hearing the name of Hari or Rama once, you shed tears and your hair stands on end, then you may know for certain that you do not have to perform such devotions as the sandhya any more. Then only will you have a right to renounce rituals; or rather, rituals will drop away of themselves. Then it will be enough if you repeat only the name of Rama or Hari, or even simply Om.
... The sandhya merges in the Gayatri, and the Gayatri merges in Om.
The awareness and conviction that fire exists in wood is jnana, knowledge. But to cook rice on that fire, eat the rice, and get nourishment from it is vijnana. To know by one's inner experience that God exists is jnana. But to talk to Him, to enjoy Him as Child, as Friend, as Master, as Beloved, is vijnana. The realization that God alone has become the universe and all living beings is vijnana.
