A favorite story of the Rebbe, central to his activist view of life:
Rabbi Schneur Zalman of Liadi, the first rebbe of the Lubavitch dynasty, led the services for Yom Kippur, the holiest day of the year.
He stood wrapped in his prayer shawl, profoundly entranced in the cleaving of his soul to its origin in the Infinite Light. Every word of prayer he uttered was fire. His melody and fervor carried the entire community off to the highest and the deepest journey of the spirit.
And then he stopped. He turned, cast off his prayer shawl and left the synagogue. With a bewildered congregation chasing behind, he walked briskly to the outskirts of town, to a small dark house from where was heard the cry of a newborn infant. The rabbi entered the house, chopped some wood and lit a fire in the oven, boiled some soup and cared for the mother and child who lay helpless in bed.
Then he returned to the synagogue and to the ecstasy of his prayer.
The Rebbe added:
Note that the rabbi removed his prayer shawl. To help someone, you must leave your world, no matter how serene, to enter the place where that person lives.

Who is pious? The person that davens all the time, and is deaf to his surroundings? Or is it the person, that while attuned to H' is also part of the social fabric in the society in which he/she lives? Jewish tradition tells us that the second type of person is doing the correct thing by addressing a need, and acting on that need. H' sees that as beneficial as it is prayer. Prayer is always important but so are human needs and if somebody can help should help. Pious prayer is important but not enough!
