For me the mysticism described in our Writings especially the Hidden Words and the Seven Valleys and the Four Valleys is a good representation of mysticism and the Baha'i faith:
I am wondering why the tie of love was so abruptly severed, and the firm covenant of friendship broken. Did ever, God forbid, My devotion lessen, or My deep affection fail, that thou hast thus forgot Me and blotted Me from thy thoughts?
What fault of Mine hath made thee cease thy favors?
Is it that We are lowly and thou of high degree? [1]
[1 Sa'di, Muslihu'd-Din of Shiraz (ca. 1184-1291), famed author of the Gulistan and other poetical works.] 48
Or is that a single arrow hath driven thee from the battle? [1]
Have they not told thee that faithfulness is a duty on those who follow the mystic way, that it is the true guide to His Holy Presence? "But as for those who say, 'Our Lord is God,' and who go straight to Him, the angels shall descend to them...." [2]
[1 Persian proverb describing a man who gives up easily. As used here one connotation is that the Shaykh might have considered his station as a mystic leader compromised by the fact of his being taught the new truth by Bahá'u'lláh.]
[2 Qur'án 41:30.]
Likewise He saith, "Go straight on then as thou hast been commanded." [1] Wherefore, this course is incumbent on those who dwell in the presence of God.
[1 Qur'án 11:114; 42:14.]
I do as bidden, and I bring the message,
Whether it give thee counsel or offense. [1]
[1 Sa'di.]
(Baha'u'llah, The Four Valleys)
