According to scripture, before becoming a monk, the Buddha was also "familiar with secular knowledge". Besides, Li Shutong, Nan and some famous masters also want to hear more. There is a saying in the Bodhisattva precept that "you can't learn heretical classics", but there is a premise that you can learn them when you use them to "measure people". Moreover, when a man of practice reaches a certain level, he must, and must, learn the classics of heretics in order to "learn from heretics" and better serve all beings.
2, the goal is to follow the path of Bodhisattva, until the achievement of Buddha fruit, we must listen more.
When you die in bliss and get rid of reincarnation, like many people, such as those who kill pigs, look after graves and look after the elderly, you can do it as long as you are sincere, diligent and mature, and you don't have to "listen more". For example, Zhou Lipanto, a famous Buddhist disciple, forgot the second sentence after teaching the first sentence, but you can achieve something. Not everyone believes in Buddhism when they walk the Bodhisattva Road, but there will be many heretics. If you want to receive them, you must know them, so you must hear more.
