Polarity

[Minyatur]

Something worth noting about polarity in the STO/STS sense, before we get too deep into equating them, is that one is described as "the path of what is" and the other is described as "the path of what is not."  These refer to what is or is not true at the level of ultimate reality.  The Logos, who is the original individuated manifestation of Infinity from whom all that we experience originates, is Love.  He is not "hatred honed to a fine edge" which is how STS derive their power.

Ra: I am Ra. Only up to a very short point. After this point, the many-ness of distortions are equal one to another. The first distortion, free will, finds focus. This is the second distortion known to you as Logos, the Creative Principle or Love. This intelligent energy thus creates a distortion known as Light. From these three distortions come many, many hierarchies of distortions, each having its own paradoxes to be synthesized, no one being more important than another.
[...]Love/light is the enabler, the power, the energy giver. Light/love is the manifestation which occurs when light has been impressed with love.

The STS path is one of pretending that something that is ultimately false (separation) exists, and building power on that illusion.  But the universe which both STS and STO inhabit is one built by Oneness out of Love; and that Love is what continues to exist beyond polarity, in the pure light after the shadows have fallen away.

Every negative emotion do come from Love, STO is but one polarity of this Love. I think it is important to note that Ra is not above polarities and has a way of embellishing his own path. At some point, both polarities are left behind for a Light/Love that is greater than both of them.
