Ever came across your mind that listening to the Dharma with a careless attitude will just be planting a virtuous seed? The seed will still sprout and mature in the end, but at a slower speed.
Our teachers remind us solemnly that there’s no such thing as taking our time to slowly plant the seed where, when the time comes, the attainment will drop from the sky and make us an instant Buddha. When the time comes, we still have to go through the cultivation process accordingly before our attainment.
