Greed for enlightenment and immortality is no different than greed for material wealth. It is self-centered and dualistic, and thus an obstacle to true attainment. Therefore these states are never achieved by those who covet them; rather, they are the reward of the virtuous.
Sincere words are not fine; fine words are not sincere. Those who are skilled (in the Tao) do not dispute (about it); the disputatious are not skilled in it. Those who know (the Tao) are not extensively learned; the extensively learned do not know it.
Don't think you can attain total awareness and whole enlightenment without proper discipline and practice. This is egomania. Appropriate rituals channel your emotions and life energy toward the light. Without the discipline to practice them, you will tumble constantly backward into darkness.
