Buddha is nothing, but Buddha is inconceivable

Buddha Himself said that if anyone wants to fully understand, fully know about the Buddha then one must see that Buddha is formless, Buddha is soundless, Buddha is nothing, but Buddha is inconceivable. Buddha is nothing. [You] shouldn’t think Buddha is something, but Buddha is inconceivable. Buddha is not nothing but Buddha is not something, either, because Buddha is beyond concepts. Therefore, because Buddha is beyond concepts, Buddha is inconceivable so He has many many ways to teach Dharma. And Buddha is able to give great great Methods, instructions according to beings’ faculties.
