Mainyo-i-Khard 47

The sage asked the spirit of wisdom

thus: 'How is the dwelling of the understanding and intellect and seed of men in the body?'

The spirit of wisdom answered

thus: 'The place of the understanding and intellect and seed of men is in the brain of the head.

And when the brain of the head is sound, the understanding and intellect and seed are on the increase;

but when a person attains unto old age, the brain of the head remains only at a diminution.

And he who is an aged man, on account of the diminution of understanding and intellect, sees less and knows less of that which it is necessary to do with wisdom. 8. Wisdom, in the beginning, mingles with the marrow of the fingers of men's hands; (9) and, afterwards, its seat and abode and place are in the heart. IO. And its dwelling in the whole body becomes such as the shape of the foot in various shoes (mûgkakŏ).'
