I. 216 (tr. Robert Fagles).
Odyssey (c. 725 BC)

Variant: I think the idea is that every person has to live for his or her own life and then make the choice to share it with other people.

Context: Every person has his own ideas of the act of praying for God's guidance, tolerance, and mercy to fulfill his duties and responsibilities. My own concept of prayer is not as a plea for special favors nor as a quick palliation for wrongs knowingly committed. A prayer, it seems to me, implies a promise as well as a request; at the highest level, prayer not only is a supplication for strength and guidance, but also becomes an affirmation of life and thus a reverent praise of God.

Context: Though the West has accepted as its teacher him who boldly proclaimed his oneness with his Father, and who exhorted his followers to be perfect as God, it has never been reconciled to this idea of our unity with the infinite being. It condemns, as a piece of blasphemy, any implication of man's becoming God. This is certainly not the idea that Christ preached, nor perhaps the idea of the Christian mystics, but this seems to be the idea that has become popular in the Christian west.
But the highest wisdom in the East holds that it is not the function of our soul to gain God, to utilise him for any special material purpose. All that we can ever aspire to is to become more and more one with God. In the region of nature, which is the region of diversity, we grow by acquisition; in the spiritual world, which is the region of unity, we grow by losing ourselves, by uniting. Gaining a thing, as we have said, is by its nature partial, it is limited only to a particular want; but being is complete, it belongs to our wholeness, it springs not from any necessity but from our affinity with the infinite, which is the principle of perfection that we have in our soul.
