The portal acting as intermediary between the limitlessness of the vibrational and the limitedness of the emotional, mental, and physical. The primary perceptual capacity of the heart is insight (seeing inward to the vibrational), which resonates initially through felt-perception. Once felt-perception is sufficiently developed, inner seeing and hearing capacities to engage directly with light and sound emanating from the vibrational are also awakened. The heart is the doorway between The Kingdom and the boredom.
