Listen to the children. Allow children to easily fill you from the deep well of their trusting hearts, the same love they give to a new kitten or puppy. Go to the park and observe the children. Let them teach you their wonderful and wacky sense of humor and joy. Give them your childishness.
Children are our teachers.
Open your mind to them. Your greatest task is to surrender to their teachings. They are transmitters of Universal Wisdom. They know what wisdom is. They live there.
