Sefer HaBahir 15
1[Rabbi Bun continued,] "And to what is [the letter] Bet similar? To a person that it is formed with wisdom: closed on all sides but open in its front. [But] the [letter] Aleph is open from its back. This is to say that the tail of the Bet is open from behind, and if it were not thus, humans would not be sustained. So too, if it were not for the Bet in the tail of the Aleph, the world would not be sustained."

«And I will breathe my praise to you» — Sefer HaBahir 5
Breath is one for all: everyone lives by it, whoever they are and whatever they believe. Every day at 11:11 local time people stop for sixty seconds, breathe, and thank GOD for the breath — each in their own words, each within themselves. In that minute we are One Breath.
WEBREATH — the Minute at 11:11, your own local time — we are One Breath
