I have read from scriptures about psychic and supernatural powers of Buddha and arahats: for example, just after birth the Buddha walked some steps on lotus flowers, elevated during meditation in his childhood, occurrence of earthquake when he touched the earth at the moment of enlightenment, ability to spread water and fire, communication with gods without physical body, ability to read mind of others, recall past lives etc.
The above are accepted only based on our faith to Buddha is reasonable: but in front of rationalists' point of view the above can't be explained; and so,
- Do we have to maintain silence as Buddhists?
- Do supernatural and psychic phenomena really exist, if so why does nobody take the challenge of rationalists (see e.g. List of prizes for evidence of the paranormal)
I mean not "psychic powers" up to Buddha's level; just for example to describe precisely certain object in a black box (also refer to Abraham Kovoor's challenge).
