"Foremost I would like to tell you that an enlightened essence is present in everyone. It is present in every state, both samsara and nirvana, and in all sentient beings; there is no exception. Experience your buddha nature, make it your constant practice, and you will reach enlightenment. In my lifetime I have known many, many people who attained such and enlightened state, both male and female. Awakening to enlightenment is not an ancient fable. It is not mythology. It actually does happen. Bring the oral instructions into your own practical experience and enlightenment is indeed possible; it is not just a fairy tale.
