Tao of Lao Tzu - 7.

'' The teaching of the Integral Way will go on as long as there is a Tao and someone who wishes to embody it; What is painted in these scrolls today will appear in different forms in many generations to come. These things, however, will never change: Those who wish to attain oneness must practice undiscriminating virtue. They must dissolve all ideas of duality: good and bad, beautiful and ugly, high and low. They will be obliged to abandon any mental bias born of cultural or religious belief. Indeed, they should hold their minds free of any thought which interferes with their understanding of the universe as a harmonious oneness. The beginning of these practices is the beginning of liberation. ''
