One’s entire life is a continuous process of learning. Any process of inquiry is related to learning. But basically our inquiry should be concerned with finding out what is transient and what is permanent. This is true knowledge.
Whatever we are doing, believing, thinking, desiring, understanding, feeling – if we are not aware of them while aware of ourselves in the present – we are asleep, and all are but embers of a dream.
True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance… To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
