He also thought that using any one of the numerous methods to learn Buddhism is equally fine, such as the Pure Land sect’s focus on single-mindedly praying to Amitabha or Zen school’s experiential realization through meditation. But it would be wrong to consider one school’s method the single most appropriate way to learn over all others.  Likewise, there are respective precepts for the monastics and lay practitioners.  One should not think that only the monastic precepts are real precepts, or that observing the lay precepts cannot help one attain Buddhahood. In Vajrayana Buddhism, there are practices involving the subtle energy system of the body, but it is not the only method one can use to attain enlightenment. All these are just different ways to reach the same destination. No one particular method is absolutely required. The only unchanging essentials, however, are wisdom and compassion. On the other hand, a method that cannot engender wisdom and compassion in the end would not be deemed the practice of the Dharma. This is the point held by Rongzom Pandita, but both the exoteric and the esoteric school also concur.
