Metaphysical meaning of gate (rw)
gate, narrow--The spiritual mind, which requires absolute conformity to Truth and measures all things by the gauge of Truth. The way is "straitened" because it requires only Truth to be recognized, and it rules out untruth or evil.
gate, wide--The easy, negative way by which men conform to sense consciousness and the pleasures of the world, with the result that their mind-muscle becomes soft and flabby. When trials come men find that they are not able to cope with them.
