The first childhood dreams contain the samskaras, the archetypes.
It is thus in no way surprising that we find obvious cakras or mandalas in children’s drawings.
Small children are very old; later on we soon grow younger. In our middle age we are youngest, precisely at the time when we have completely or almost completely lost contact with the collective unconscious, the samskaras.
We grow older again only as with the mounting years we remember the samskaras anew. ~Carl Jung, Kundalini Yoga Seminar, Pages 73-74.
