There is no comparison between Him and any other

We are always in a hurry. [But] if any great work is to be done, there must be great preparation. … After much praying, day and night, Mohammed began to have dreams and visions. Gabriel appeared to him in a dream and told him that he was the messenger of truth. He told him that the message of Jesus, of Moses, and all the prophets would be lost and asked him to go and preach. Seeing the Christians preaching politics in the name of Jesus, seeing the Persians preaching dualism, Mohammed said: “Our God is one God. He is the Lord of all that exists. There is no comparison between Him and any other.”

Knowledge is Better than Action-the Highest Form of Life

“From ancient times these two systems have come down to us. The Sânkhya philosophers advance the theory of knowledge. The Yogis advance the theory of work. But none can attain to peace by renouncing actions. None in this life can stop activity even for a moment. Nature’s qualities [Gunas] will make him act. He who stops his activities and at the same time is still thinking about them attains to nothing; he only becomes a hypocrite. But he who by the power of his mind gradually brings his sense-organs under control, employing them in work, that man is better. Therefore do thou work.”

The battlefield of Kurukshetra, Begins the Gita

The Gita opens with this very significant verse: “Arise, O Prince! Give up this faint-heartedness, this weakness! Stand up and fight!” (Gita, II. 3.) Then Arjuna, trying to argue the matter [with Krishna], brings higher moral ideas, how non-resistance is better than resistance, and so on. He is trying to justify himself, but he cannot fool Krishna. Krishna is the higher Self, or God. He sees through the argument at once. In this case [the motive] is weakness. Arjuna sees his own relatives and he cannot strike them. …

The Gita is a commentary on the Upanishads

The Gita is a commentary on the Upanishads. The Upanishads are the Bible of India. They occupy the same place as the New Testament does. There are [more than] a hundred books comprising the Upanishads, some very small and some big, each a separate treatise. The Upanishads do not reveal the life of any teacher, but simply teach principles. They are [as it were] shorthand notes taken down of discussion in [learned assemblies], generally in the courts of kings. The word Upanishad may mean “sittings” [or “sitting near a teacher”]. Those of you who may have studied some of the Upanishads can understand how they are condensed shorthand sketches. After long discussions had been held, they were taken down, possibly from memory. The difficulty is that you get very little of the background. Only the luminous points are mentioned there.

Krishna-The fact is, who is unique in spirituality.

This Krishna preceded Buddha by some thousand years. … A great many people do not believe that he ever existed. Some believe that [the worship of Krishna grew out of] the old sun worship. There seem to be several Krishnas: one was mentioned in the Upanishads, another was king, another a general. All have been lumped into one Krishna. It does not matter much. The fact is, some individual comes who is unique in spirituality. Then all sorts of legends are invented around him. But, all the Bibles and stories which come to be cast upon this one person have to be recast in [the mould of] his character. All the stories of the New Testament have to be modelled upon the accepted life [and] character of Christ. In all of the Indian stories about Buddha the one central note of that whole life is kept up — sacrifice for others. …
