Here is a suggested reading for this Feast:
They who are the beloved of God, in whatever place they gather and whomsoever they may meet, must evince, in their attitude towards God, and in the manner of their celebration of His praise and glory, such humility and submissiveness that every atom of the dust beneath their feet may attest the depth of their devotion. The conversation carried by these holy souls should be informed with such power that these same atoms of dust will be thrilled by its influence.
