From the Chohan Letter of 1881:
...It's time that Theosophy should enter the arena. The sons of Theosophists are more likely to become in their turn Theosophists than anything else. No messenger of truth, no prophet has ever achieved during his life time a complete triumph, not even Buddha; the Theosophical Society was chosen as the corner stone, the foundation of the future religion of humanity. To achieve the proposed object a greater, wiser, and especially a more benevolent intermingling of the high and the low, of the alpha and the omega of society, was determined upon. The white race must be the first to stretch out the hand of fellowship to the dark nations, to call the poor despised "nigger" brothers. This prospect may not smile to all. He is no Theosophist who objects to this principle. . . .
From the KH Letter of 1900:
...The T.S. was meant to be
the corner-stone of the future religions of humanity. To accomplish this
object those who lead must leave aside their weak predilections for
the forms and ceremonies of any particular creed and show themselves to be true
Theosophists both in inner thoughts and outward observance....
