I do not understand this squeamishness about the use of gas... I am strongly in favour of using poisoned gas against uncivilised tribes... It is not necessary to use only the most deadly gases: gases can be used which cause great inconvenience and would spread a lively terror and yet would leave no serious permanent effects on most of those affected.
The true Way is sublime. It can't be expressed in language. Of what use are scriptures? But someone who sees his own nature finds the Way, even if he can't read a word.
