Since intelligence is the highest manifestation of matter, it is logically the lowest manifestation of consciousness, or spirit, and Jupiter (or the personal I) is enshrined in the substances of mortal mind where he controls his world through what man is pleased to term intellect. The Jupiterian intellect, however, is that which sees outward or towards the illusions of manifested existence, whereas the higher, or spiritual, mind (which is latent in most individuals) is that superior faculty which is capable of thinking inward or towards profundities of Self; in other words, is capable of facing towards and gazing upon the substance of Reality. Thus the mind may be likened to the two-faced Roman god Janus. With one face this god gazes outward upon the world and with the other inward towards the sanctuary in which it is enshrined. The two-faced mind is an excellent subject for meditation. The objective, or mortal, mind continually emphasizes to the individual the paramount importance of physical phenomena; the subjective, or immortal, mind if given opportunity for expression combats this material instinct by intensifying the regard for that which transcends the limitations of the physical perceptions.
