Joy and sorrow are the light and shade of life; without light and shade no picture is clear.
Hazrat Inayat KhanIt 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.
Hazrat Inayat Khan
