Peace...

Peace is perfected activity; that is perfect which is complete in all its aspects, balanced in each direction and under complete control of the will.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

It is useless to discuss the peace of the world. What is necessary just now is to create peace in ourselves that we, ourselves, become examples of love, harmony and peace. That is the only way of saving the world and ourselves.

Peace is independently felt within oneself. It is not dependent upon the outer sensation. It is something that belongs to one, something that is one's own self. ... Peace is not a knowledge, peace is not a power, peace is not a happiness, but peace is all these. And besides, peace is productive of happiness. Peace inspires one with knowledge of the seen and unseen, and in peace is to be found the divine Presence. It is not the excited one who conquers in this continual battle of life. It is the peaceful one who tolerates all, who forgives all, who understands all, who assimilates all things. The one who lacks peace, with all his possessions, the property of this earth or quality of mind, is poor even with both. He has not got that wealth which may be called divine and without which man's life is useless. For true life is in peace, a life which will not be robbed by death.

The secret of mysticism, the mystery of philosophy, all is to be attained after the attainment of peace. You cannot refuse to recognize the divine in a person who is a person of peace. It is not the talkative, it is not the argumentative one, who proves to be wise. He may have intellect, worldly wisdom, and yet may not have pure intelligence, which is real wisdom. True wisdom is to be found in the peaceful, for peacefulness is the sign of wisdom. It is the peaceful one who is observant. It is peace that gives him the power to observe keenly. It is the peaceful one, therefore, who can conceive, for peace helps him to conceive. It is the peaceful who can contemplate; one who has no peace cannot contemplate properly. Therefore, all things pertaining to spiritual progress in life depend upon peace.

And now the question is what makes one lack peace? The answer is, love of sensation. A person who is always seeking to experience life in movement, in activity, in whatever form, wants more and more of that experience. In the end he becomes dependent upon the life which is outside, and so he loses in the end his peace, the peace which is his real self. ... the first thing is to seek the kingdom of God within ourselves, in which there is our peace. As soon as we have found that, we have found our support, we have found our self. And in spite of all the activity and movement on the surface, we shall be able to keep that peace undisturbed if only we hold it fast by becoming conscious of it.
