Last night I finished Gregory's
Treatise on the Spiritual Life, and much of your blog is taken directly from that text. For example, a different translation:
And what is most paradoxical--this is done by the inexpressible light which radiates the inner parts and perfects the inner self. "Until the day dawns and the morning star rises in your hearts," (2 Pet 1:19) according to the chief among the apostles, the true human being "goes forth," according to that prophetic saying, "to one's work and labor until evening," (Ps 103:23) and by using this light as a path, ascends, or rather is led upward "to the eternal mountain" (Ps 75:5). And in this light one is made a visionary of celestial things, O wonder!

Likewise, St. Isaac says: "During the time of prayer, the graced intellect sees its purity, which is like the heavenly colors, which the Israelite elders named, 'the place of God,' (Ex 24:10) when God appeared to them on the mountain." And again: "There is the purity of the intellect which during the time of prayer radiates the light of the Holy Trinity."
But the intellect which is worthy of that light transmits to the body which is united to it many beautiful signs of divinity, mediating between divine grace and fleshly imperviousness, granting power to that which is of itself powerless. From here follows the God-like and incomparable inclination towards virtue, which is completely immovable and insusceptible to evil. Next the Logos who discloses the principles of existence, reveal, out of His own purity, the inner mysteries of nature; and through them, by way of analogy, the noetic faculty of the faithful listeners is lifted upward towards the perception of that which is beyond nature--a perception of Whom, by its own contacts, remains Himself the Father of the Logos.
