As a matter of experience, this is all there is …
The Buddha said:
Siddhartha Gotama, in the Samyutta Nikaya (Connected Discourses of the Buddha)
I will teach you the all. Listen closely. What is the all? It is the eye and forms, the ear and sounds, the nose and odors, the tongue and tastes, the body and tactile sensations, the mind and thinking. This is called the all. Some might say, ‘This all is not enough. I reject this all. I will proclaim another all.’ But because this is a groundless assertion, such people, when asked about it, would not be able to show another all because that all is not within their sensorium. Such an assertion would merely be a thought arising in their minds.
