If you really want to seek the true meaning of Nirvana, first of
all, you have to learn how to release your attachments, especially
attachment of your own perceptions, your own views, your own
thinking, next is attachment to your body. I don't know whether you
will classify that as to Let Go. Maybe once you could do that, the
rest of the brothers like AEN and NO will be able to guide you
further in your path of cultivation, IF you are truely interested
in seeking the truth that you've wanted in Buddhism. No point
spending precious time debating for the sake of debating,
ultimately, you'll gain nothing out of it.
Be humble and accept dharma teachings with an open mind. You have
the wisdom, so don't misuse it.
