STS polarization question

[anagogy]

"You may, with some fruitfulness, consider the possibilities of moonlight. You are aware that we have described the Matrix of the Spirit as a night. The moonlight, then, offers either a true picture seen in shadow or chimera and falsity. The power of falsity is deep as is the power to discern truth from shadow. The shadow of hidden things is an infinite depth in which is stored the power of the One Infinite Creator.

The adept, then, is working with the power of hidden things illuminated by that which can be false or true. To embrace falsity, to know it, to seek it, and to use it gives a power that is most great. This is the nature of the power of your visitor and may shed some light upon the power of one who seeks in order to serve others as well, for the missteps in the night are oh! so easy."

I am having a bit of trouble understanding this quote. Is Ra saying that the negative adept creates illusion in perception using the "shadow of night" to deceive an individual? That the adept will offer the truth, though it will be shrouded in trickery in order to confuse or disempower an individual.

Ra is saying that both negatively, and positively, polarized individuals gain the spiritual power to discern truth from falsehood. The STS, however, use this ability to even more powerfully deceive others for the purposes of manipulation. The STO would use this power to discern truth from falsehood in order to enlighten and empower others. The STS use the power of discernment for self empowerment, which, necessarily involves withholding the power (which is truth) from others.
