The Scientific mantra


(Pratyakha anumaana agaamah pramaaNaani)

Pratyaksha: Direct observation
Anumaana: Inference
Agaamah: Authority
PramaaNaani: Knowledge

This is a shloka from Patanjali's Yogasutra about the nature of knowing the truth. PramaaNa is true knowledge, and can be obtained either by
(1) direct observation,
(2) inference from a set of events; or,
(3) on the authority of someone who has done (1) or (2).

In a concise manner, it encodes the entire method and practice of science as developed and followed by the Greeks and their intellectual descendants. Strange that the Yogasutra became a source of a lot of mysticism (and a common form of exercise) instead!
