I have finally decided to write my book on the spiritual life. I mean to put down as simply as possible the sort of ascetical or mystical teaching that I have been living and preaching so long. I call it 'Le Milieu Divin,' but I am being careful to include nothing esoteric and the minimum of explicit philosophy.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.

I greatly enjoyed the Hawaiian Islands. They are a real little paradise in spite of the influx of Americans who have made it one of their most pleasant 'centers of resort': the soft climate and luxuriance of the tropics; the greenness, the fragrance, the flowers - extraordinary flowers covering the tallest trees and turning them into huge bouquets.

There is neither spirit nor matter in the world. The stuff of the universe is spirit-matter. No other substance but this could have produced the human molecule.

Everywhere on Earth, at this moment, in the new spiritual atmosphere created by the appearance of the idea of evolution, there float, in a state of extreme mutual sensitivity, love of God and faith in the world: the two essential components of the Ultra-human.

I give the name of cosmic sense to the more or less confused affinity that binds us psychologically to the All which envelops us. The existence of this feeling is indubitable, and apparently as old as the beginning of thought... The cosmic sense must have been born as soon as man found himself facing the forest, the sea and the stars.

The problem of evil, that is to say the reconciling of our failures, even the purely physical ones, with creative goodness and creative power, will always remain one of the most disturbing mysteries of the universe for both our hearts and our minds.

Nothing can resist the person who smiles at life - I don't mean the ironic and disillusioned smile of my grandfather, but the triumphant smile of the person who knows that he will survive, or that at least he will be saved by what seems to be destroying him.

The Church is like a great tree whose roots must be energetically anchored in the earth while its leaves are serenely exposed to the bright sunlight. In this way, she sums up a whole gamut of beats in a single living and all-embracing act, each one of which corresponds to a particular degree or a possible form of spiritualisation.

The more nobly a man wills and acts, the more avid he becomes for great and sublime aims to pursue. He will no longer be content with family, country, and the remunerative aspect of his work. He will want wider organisations to create, new paths to blaze, causes to uphold, truths to discover, an ideal to cherish and defend.

How great is the mystery of the first cells which were one day animated by the breath of our souls! How impossible to decipher the welding of successive influences in which we are forever incorporated! In each one of us, through matter, the whole history of the world is in part reflected.

For me, the Immaculate Conception is the feast of 'passive action,' the action that functions simply by the transmission through us of divine energy. Purity, in spite of outward appearances, is essentially an active virtue, because it concentrates God in us and on those who are subject to our influence.

Death surrenders us totally to God: it makes us enter into him; we must, in return, surrender ourselves to death with absolute love and self-abandonment since, when death comes, all we can do is to surrender ourselves completely to the domination and guidance of God.

Evolution is a light illuminating all facts, a curve that all lines must follow.

One mustn't close one's eyes to difficulty and to shortcomings; the more one recognizes them, the less they upset one.

If there is one thing I fear less than everything else, it is, I believe, persecution for my opinions. There are a good many points about which I may be diffident, but when it comes to questions of Truth and intellectual independence, there is no holding me - I can envisage no finer end than to sacrifice oneself for a conviction.

Man can be understood only by ascending from physics, chemistry, biology, and geology. In other words, he is first of all a cosmic problem.

He that will believe only what he can fully comprehend must have a long head or a very short creed.

Driven by the forces of love, the fragments of the world seek each other so that the world may come to being.

A sense of the universe, a sense of the all, the nostalgia which seizes us when confronted by nature, beauty, music - these seem to be an expectation and awareness of a Great Presence.

Death is acceptable only if it represents the physically necessary passage toward a union, the condition of a metamorphosis.

Love is the affinity which links and draws together the elements of the world... Love, in fact, is the agent of universal synthesis.

The earth's crust has not yet stopped heaving and plunging under our feet. Mountain ranges are still being thrust up on the horizon. Granites are still growing under the continental masses. Nor has the organic world ceased to produce new buds at the tips of its countless branches.

We spend our lives, all of us, waiting for the great day, the great battle, or the deed of power. But that external consummation is not given to many: nor is it necessary. So long as our being is tensed, directed with passion, towards that which is the spirit of all things, then that spirit will emerge from our own hidden, nameless effort.
