Haruki Murakami said this quote
“ I feel very strongly that all Japanese at that time had the idea drilled into them of 1999 being the end of the world. Aum renunciates have already accepted, inside themselves, the end of the world, because when they become a renunciate, they discard themselves totally, thereby abandoning the world. In other words, Aum is a collection of people who have accepted the end. People who continue to hold out hope for the near future still have an attachment to the world. If you have attachments, you will not discard your Self, but for Renunciates it's as if they've leaped right off the cliff. And taking a giant leap like that feels good. They lose something - but gain something in return. ”
