Asher, the son of Jacob, was born on the 20th of Shevat of the year 2199 from creation (1562 BCE). According to some accounts, this is also the date of his passing.
On Simchat Torah we dance with our feet, not with our heads.
We are celebrating the Torah, and the Torah is something we study with our heads. But we dance with our feet, not with our heads.
If we would dance with our heads, each one would dance a different dance, each in a different space, some with friends but not with others, some as lonesome souls.
One head is higher, one is lower, one is here on earth, the other in the clouds or beyond, and some minds know only their own space that no one else can know.
But we dance with our feet, and all our feet are here on the same earth—none higher and none lower. So now we can all dance as one, with one heart, as a single being.
Now there is no loneliness, only joy.
