A stimulant has been traded for access, and everything turns on where that rising energy is directed. The mandrakes are the aroused force gathered from the field of the body, and Leah, the weary side, buys the seed with them and draws it down into the emotional nature where it spends itself and leaves the person tired again. This is the exchange happening in a person whenever a quickened current is pulled toward feeling and craving rather than lifted. The evening is the dimming of clear awareness in which such bargains are struck, and the field is the body from which the stimulus is harvested. The same force, if it filtered upward instead of down, would unite a person with the higher father, but here it is spent on the weary side and the night closes over it.
