I have been practising Buddhism and meditation in the Theravadin tradition for the best part of 20 years and have 'lurked' on this site for a while now. I thought some of you may be interested to look at a site devoted to Buddhist meditation that is entirely stripped of all cultural accretions and approaches the practise of meditation as almost a scientific endeavour aimed at the attainment of enlightenment in this lifetime. Check out http://www.dharmaoverground.org/web/guest/home.
This approach to meditation is completely in line with the Buddha's teachings on practise and the stages of the path and requires a lot of hard work and a very critical attitude towards the reality of your own experiences. However, I have found that practising in this way has given me a new focus and the reading the advice of forum members on the site has been invaluable in helping me overcome obstacles I have wrestled with in meditation for years. I hope other people may derive some benefit from this online Dhamma community.
