Kwan-shai-yin

Kwan-Shai-Yin, Kuan-Shi-Yin (Chinese) Equivalent to the Sanskrit Avalokitesvara, both being the seventh kosmic principle. Mystically, the kosmic Logos or Word, and in common with all the logoi referred to as a kosmic Dragon of Wisdom; the first universal manus or kosmic dhyan-chohans.
Kwan-shai-yin is often confused with Kwan-yin, the Chinese goddess of compassion, the feminine Logos and counterpart of Kwan-shai-yin; but "Kwan-shai-yin -- or the universally manifested voice 'is active -- male; and must not be confounded with Kwan-yin, or Buddhi the Spiritual Soul (the sixth Pr.) and the vehicle of its "Lord." ' It is Kwan-yin that is the female principle or the manifested passive, manifesting itself 'to every creature in the universe, in order to deliver all men from the consequences of sin'. . . while Kwan-shai-yin, 'the Son identical with his Father' is the absolute activity, hence -- having no direct relation to objects of sense is -- Passivity" (ML 344).
Kwan-shai-yin, the Voice or Logos, is "the germ point of manifested activity; -- hence -- in the phraseology of the Christian Kabalists 'the Son of the Father and Mother,' and agreeably to ours -- 'the Self manifested in Self -- Yih-sin, the 'one form of existence,' the child of Dharmakaya (the universally diffused Essence), both male and female" (ML 346).
In man it is the atman when working through -- as it always does during imbodiment -- its veil buddhi, thus enabling the atman to send down and distribute the atmic rays throughout the other five principles of the human constitution.
