Where did Buddhism come from?

"Although the rain is wide, the grass has no roots, and Buddhism is not wide." This is the couplet at the back door of Baima Temple.

Literally: although the rain in the sky covers a wide area and moistens everything on the earth, it can't moisten rootless grass, because grass absorbs water through its roots, and even if it is soaked in water, it can't moisten it. Although Buddhism is everywhere, including all aspects around us, there is no chance for those who have no chance to be redeemed in this life. It is only "external cause" and "internal cause" for the Buddha to judge people (I accept). If I don't accept it, it will be in vain. Just like a person trapped in a tree by a flood, if someone comes to the boat to save you, the only way to be saved is to get on the boat. How can you be saved if you refuse to board the ship?

Buddhism pays attention to cause and effect, and the reason is simple. Just like if you want to harvest food, you must sow. After many processes, at a mature moment, it will form rich fruits. Seeds are cause, food is fruit, and causality can also be called fate.

The Buddhism is vast, and it will be ruthless without crossing it, but it is a fact, and even the Buddha cannot subvert the cause and effect. There is a story in the Buddhist scriptures: One day, the Buddha and his disciples went out and the disciples saw an old woman. The old woman is poor, and poverty and illness afflict her. Both the Buddha and his disciples are merciful people, so the disciples asked the Buddha if he could help her, but the Buddha said he couldn't help her because this woman had never had a relationship with Buddhism in many cycles in the past. How can there be a result without a reason? The Buddhist disciples didn't believe it, so they called this woman, hoping to preach a Buddha to save the degree. But she turned a deaf ear and couldn't hear anything. The disciples went to her, hoping to attract her attention, but she turned away, the disciples walked behind her, and she turned to the front ... that is to say, from beginning to end, she could not see the Buddha and his disciples. The Buddha disciple wanted to find her, but she actually left, just like a repulsive magnet, which could not be put together because there was no fate.
