Once this affinity ends, the Buddha will enter Nirvana. The Buddha teaches us that we need to search our true self from within, not from the outside. To search from the outside would be superstitious and futile. The need is for one to end one's afflictions, greed, anger, ignorance and arrogance that block our true self from coming through. Meditating is settling the mind, not just the practice of sitting in the lotus position on a cushion or platform while having wandering thoughts, one after another.
Concentration is when no afflictions arise from within.
He, who regards others as Buddhas, is a Buddha, while an ordinary person would regard the Buddha as ordinary. In other words, an evil person would regard all as evil, whereas, a virtuous person would regard all as kind and virtuous. In reality, there is no good or bad, beautiful or ugly in the world but just reflections from our mind. The outside environment changes according to one's state of mind. When one sees other persons as displeasing, disgusting, etc., this perception comes from the afflictions arising from within one's own mind and has nothing to do with exterior factors.
