Music is intangible and ephemeral, but it comes from the home world of the spirit, and though so fleeting, it is recognized by the spirit as a soul-speech fresh from the celestial realms, an echo from the home whence we are now exiled, and therefore it touches a cord in our being, regardless of whether we realize the true cause or not.
It is a mystic maxim that the lower in the scale of evolution a being is placed, the more certainly it responds to the planetary rays, and conversely the higher we ascend in the scale of attainment, the more the man conquers and rules his stars, freeing himself from the leading strings of the Divine Hierarchies.
If a situation requires sudden thought and action, the blood is promptly driven to the head. If a heavy meal is to be digested, the greater portion of the blood leaves the head, centering around the digestive organs. The Ego concentrates its efforts on ridding the body of the useless food. Therefore a man cannot think well after a heavy meal.
