“The essence of spirituality does not consist in a specialised or narrow interest in some imagined part of life, but in a certain enlightened attitude to all the various situations which obtain in life.”

Context: The difference between Christ and the other prophets is threefold:
1. Unlike the other prophets, he has no connection with politics and is not a people's tribune. In the Gospels, we find temporal circumstances only as background, Christ having no relationship to them at all. He kept his thoughts unmuddled by the world — "Get thee behind me, Satan!" — he was and remained truly free of the world.
2. He preaches no religious superficialities whatsoever, nothing at all of worship, nothing of God; he is truly godless.
3. Neither for earth nor heaven does he preach any coming kingdom. "But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you" ( Mt. 6:33 http://bible.cc/matthew/6-33.htm). The kingdom, however, is nothing that is to come; it is here, it is within you ( Lk. 17:21 http://bible.cc/luke/17-21.htm). It is the Spirit of innerness as it is alive in him, the truly blessed man; it is the essence, ever being and never changing. It is also the essence of this our life, not merely an appendix granted it by some other essence, for which we would have to fulfill certain conditions.

Answering the question "Your Holiness, there are many people in the West who want to combine their spiritual practice with social and political responsibility. Do you feel that these two aspects are connected?" in an interview with Catherine Ingram, Dharamsala, India (2 November 1988).
Context: I feel that the essence of spiritual practice is your attitude toward others. When you have a pure, sincere motivation, then you have right attitude toward others based on kindness, compassion, love and respect. Practice brings the clear realisation of the oneness of all human beings and the importance of others benefiting by your actions.

Word Play (1974)
Context: Freedom of speech does not exist anywhere, for every community on earth forbids the use of certain sounds, words, and sentences in various speech situations.... the habitual liar faces social sanctions... Speakers are not allowed to misrepresent... to defame other people in public, to maliciously shout "Fire!" in a crowded movie theater, or to utter obscenities on the telephone.

Beyond the Veil
Context: Life passes, but the conditions of life do not. Air, food, water, the moral sense, the mathematical problem and its solution. These things wait upon one generation much as they did upon its predecessor. What, too, is this wonderful residuum which refuses to disappear when the very features of time seem to succumb to the law of change, and we recognize our world no more? Whence comes this system in which man walks as in an artificial frame, every weight and lever of which must correspond with the outlines of an eternal pattern?
Our spiritual life appears to include three terms in one. They are ever with us, this Past which does not pass, this Future which never arrives. They are part and parcel of this conscious existence which we call Present. While Past and Future have each their seasons of predominance, both are contained in the moment which is gone while we say, "It is here."
So the Eternal is with us, whether we will or not, and the idea of God is inseparable from the persuasion of immortality; the Being which, perfect in itself, can neither grow nor decline, nor indeed undergo any change whatever. The great Static of the universe, the rationale of the steadfast faith of believing souls, the sense of beauty which justifies our high enjoyments, the sense of proportion which upholds all that we can think about ourselves and our world, the sense of permanence which makes the child in very truth parent to the man, able to solve the deepest riddle, the profoundest problem in all that is. Let us then willingly take the Eternal with us in our flight among the suns and stars.
Experience is our great teacher, and on this point it is wholly wanting. No one on the farther side of the great Divide has been able to inform those on the hither side of what lies beyond.
