What is the meaning of heavenly wisdom?

There is no royal road to Divine Wisdom. There is, however, a straight and narrow path to spiritual unfoldment. It is found only by wedding Knowledge to Understanding and Love to Wisdom. It must be trodden step by step, often in weariness and with bleeding feet.

If you control one selfish trait, which before held you captive, you may know that you have taken a real step upward.

And the first and greatest of all magical powers to be attained by the pupil of mysticism is the magical power of controlling himself, of day-after-day mastering the little things with no heroics, perhaps with no one to commend him or realise that he is making any effort, yet still controlling his little tempers, his little impatiences, little acts of selfishness, his tendency to criticise, and all the little, trifling things he knows are wrong, but which seem too petty to be worth mentioning.

The building of these little lessons into his life is the most practical formula that can be given to him.
