VI. Yoga In East and West II
Let us take another comparison. The higher soul is closely linked with the animal soul. By their fusion the passions are tempered, spiritualised and dominated according to the strength of man's intelligence and will. This fusion is of benefit to man but he pays for it by the loss of clairvoyance. Imagine to yourself a green liquid, produced by a combination of blue and yellow elements. If you succeed in separating them, the yellow will descend and the blue will rise to the surface. Something analogous happens when, through Yoga, the animal-soul is separated from the higher soul. The latter acquires clairvoyant vision; the former is left to its own devices if it has not been purified by the self and it is then given over to its passions and desires. This often happens in the case of mediums. The ‘Guardian of the Threshold’ protects man from this danger.
