From chapter 5 of the Maha-Parinibbana Sutta (DN16 of the Pali Canon):
Then the Blessed One said to Ven. Ananda, “Ananda, the twin sal-trees are in full bloom, even though it’s not the flowering season. They shower, strew, & sprinkle on the Tathagata’s body in homage to him. Heavenly coral-tree blossoms are falling from the sky… Heavenly sandalwood powder is falling from the sky… Heavenly music is playing in the sky… Heavenly songs are sung in the sky, in homage to the Tathagata. But it is not to this extent that a Tathagata is worshipped, honored, respected, venerated, or paid homage to. Rather, the monk, nun, male lay follower, or female lay follower who keeps practicing the Dhamma in accordance with the Dhamma, who keeps practicing masterfully, who lives in accordance with the Dhamma: that is the person who worships, honors, respects, venerates, & pays homage to the Tathagata with the highest homage.
The Maha-Parinibbana Sutta is thought to be the last teaching of the Buddha before he died. Here, he’s telling followers that if they really want to worship and honor the Buddha, they should practice what he taught.
I don’t think it matters how much. It matters if one keeps trying. 🙂
