Who is a Hindu ?

The term is found in Meru Tantra  (4 ^th to 6 ^th century AD), which says :

हीनं च दूष्यत्येव हिन्दुरित्युच्यते प्रिये ।

Meaning : One who destroys the callous and inferior Raja-Tama components is called Hindu. One who rejects these lower tendencies – whether physical, verbal, or mental – and instead embraces a Sattva predominant way of life, considers devotion to God as the essence of existence, seeks the Divine, and adheres to Karmayoga (Path of Action) to guide society, is to be called a Hindu.
