“The wise man should keep the balance between love and power; he should keep the love in his nature ever increasing and expanding, and at the same time strengthen the will so that the heart may not easily be broken.” ~Hazrat Inayat Khan
“Many seek protection from all hurting influences by building some wall around themselves. But the canopy over the earth is so high that a wall cannot be built high enough, and the only thing one can do is to live in the midst of all inharmonious influences, to strengthen his will power and to bear all things, yet keeping the fineness of character and a nobleness of manner together with an ever-living heart. To become cold with the coldness of the world is weakness, and to become broken by the hardness of the world is feebleness, but to live in the world and yet to keep above the world is like walking on the water. There are two essential duties for the man of wisdom and love; that is to keep the love in our nature ever increasing and expanding and to strengthen the will so that the heart may not be easily broken. Balance is ideal in life; man must be fine and yet strong, man must be loving and yet powerful.”
