What is the soul and how may I approach it?

[Sacred Fool]

Although I don't understand on what you meant by 'mental' and 'heart' consciousness.

The path you're on seems useful for balancing a sense of the 3D self and all its possible self-identifications.  The intended point of this thread, however, has to do with communing with the portion of self which initiates these identities, but lives well outside of 3D.  It's a place, not just of neutrality, but of transcendent acceptance, caring and inclusion.  Q'uo avers that it is accessed by 3D mortals through the passageway of the deep heart, but not merely by rearranging mental associations on a lateral 3D plane.  Entry through the looking glass of the heart opens the opportunity for direct communion with the aspect of Divinity to which we are most closely tied: our own soul.
