There are a few words of introduction by Gongdzö Ritröpa Chenpo who said that in order to achieve Enlightenment one must first meditate. In order to meditate so that we can achieve Buddhahood, we must realize the View.
“You must search for the meaning with your own mind. It is not enough to merely trust whatever Buddha said; Otherwise, the essential meaning can never be realised. Therefore, it is imperative to verify Buddha’s words with your own reason.”
