Sri Chinmoy: A beginner has to feel that he is a child, no matter how old he is in earthly age. A child's mind is not developed. When he is twelve or thirteen his mind starts functioning on an intellectual level, but before that he is all heart. Whatever he sees, he feels is his own. He identifies spontaneously. This is what the heart does.
When you feel that you are a child, immediately feel that you are standing in a flower garden. This flower garden is your heart. A child can play in a garden for hours. He will go from this flower to that flower, but he will not leave the garden, because he will get joy from the beauty and fragrance of each flower. Inside you is the garden, and you can stay within it for as long as you want. In this way you can meditate on the heart.
The moment you feel that you are a child, you can meditate on the heart. A child will always have someone to take care of him even if his physical parents are not there. God will have somebody to take care of the child, because He feels that the child is helpless right now. When a child cries, immediately someone comes to help him. But when a grown-up person cries, his cry is not even sincere. When a child cries even for a candy, he is very sincere. At that time his candy is the whole world for him. If you give him a hundred-dollar bill, he will not be satisfied; he will only care for his candy. When you feel you are crying like a child for Peace, Light and Truth, and that only those things will satisfy you, then your cry will be fulfilled.
