The Torah, “Exodus” (VaYakhel), 35:4-35:6: And Moses spoke to the entire community of the children of Israel, saying: “This is the word that the Lord has commanded to say: ‘Take from yourselves an offering for the Lord; every generous hearted person shall bring it, [namely] the Lord’s offering: gold, silver, and copper; and blue, purple, and crimson wool; and linen and goat hair…
Our heart is the ego. But when a certain inclination to bestowal, connection, and love appears in a heart and it understands that it’s impossible to go on living egoistically, it’s called a generous heart.
Today we have already realized through suffering that we should somehow change humanity: our nature, society, the connections between us, because the world has already developed and has suffered enough in order to feel disappointed with its current egoistic evolution. Therefore, the word “generous,” in the spiritual sense, means “to give.” A generous heart is the recognition of our egoistic nature and working above it.
