„The Buddha said, "Elements come together and form this body. At the time of appearing, elements appear. At the time of disappearing, elements disappear. When elements appear, I do not say "I" appear. When elements disappear, I do not say "I" disappear. Past moments and future moments do not arise in sequence. Past elements and future elements are not in alignment. This is the meaning of ocean mudra samadhi."
Closely investigate these words by the Buddha. Attaining the way and entering realization does not necessarily require extensive learning or realization. Anyone can attain the way through a simple verse of four lines. Even scholars of extensive learning can enter realization through a one line verse.“
