One meditation gives this instruction :

Imagine your heart opening into a red lotus.

From its center comes a crimson child.

Bring this child out of your body and imagine him or her floating above your head. You, as a child, are holding a sun in each hand while each foot stands on a moon.

Hold this image as long as you can.

It is hard to bring out this child. When you try, you realize how many defenses you have built around yourself. You also realize how the experiences of adolescence and adulthood have stained you. Sometimes, you may even doubt that you have a pure and innocent self to bring out anymore. But each of us does. Each of us must find that crimson child within us and bring him or her out. For this child represents the time when our energies were whole and our hearts were untroubled by the duplicity of the world and ourselves.
