Mm. They could not prevent me from committing to anything I decided to do. Physically or otherwise, I have learned this the hard way.

I do not mind, we encourage people to find out before choosing a sect to attend. My sect was based on the teaching and principle methods of a man called Lan An. He was a monk, who fell in love and discovered new ways of cultivation inspired by his life. It is quite strict, and difficult to master. All the passengers on the train with a head band and perhaps white robes are part of it.

Thank you for the kind offer, but no. They would not have any effect thanks to my cultivation burning away the impurities. If by herb you mean cannabis, I have never tried, I do not know how it would affect me.
