Balance...

There should be a balance in all our actions - to be either extreme or lukewarm is equally bad.

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

There are two forces in us, love and reason. We must keep an even balance between the two. If we give too much expression to love we become unbalanced and fall into trouble. And if on the other hand we lean too much on the side of reason we become cold.In balance lies the whole secret of life ... All religions and philosophies have laid down certain principles such as kindness, truthfulness, forgiveness, but the mystic lays no stress on principles, he allows everyone to have his own principles, each according to his point of view and evolution. For example, there are two men, one is so merciful that he will not even harm an insect, and he could not draw a sword to kill another human being, while the other man for the sake of his people is content to fight and to die. These are two opposite points of view, and both are right in their way.

The Sufi therefore believes one should let each hold on to the principle suited to his evolution, but for himself he looks beyond the principle to that which is at the back of it, the balance. He realizes that what makes one lose balance is wrong, and what makes one keep it is right. The main point is not to act against one's principles. If the whole world says a thing is wrong, and you yourself feel that it is right, it is so, perhaps, for you.

The question of balance explains the problem of sin and virtue, and he who understands it is the master of life. There should be a balance in all our actions. To be either extreme or lukewarm is equally bad. There is a saying, 'Jack of all trades, and master of none.' This is very true, as there has been too little effort given, so that no one thing has been done thoroughly.

Success, failure, progress, standstill, one's state of being, it all comes from the condition that a person is experiencing within himself. ... according to the Sufi idea the condition of life around one depends absolutely on the condition of one's inner self. So what is needed to change the conditions in outer life, or to tune oneself, is to work with one's inner self in order to bring about the necessary balance.
