"The human being is the threshold between two worlds, two realities: that of material existence, which inhabits the 'ego', and spiritual reality, where 'being' essentially remains in full union with love for free, covering everything. These two are consciously heart to heart. Without the awakening and purification of the heart, the 'ego' remains in illusion, in fear, in contention in the separation and isolation. Without a high heart to the knowledge there is no connection between the 'ego' and 'being' essential. Access to the wisdom of the heart is the central point of our being and our greatest power of knowledge. The eyes of the heart have greater range than the eyes of the intellect or the passions of our "ego". A heart that is in this condition provides the possibility of true selflessness, true wellness and true happiness. "
