From Hindupedia, the Hindu Encyclopedia
The term "Hindutva" is derived from the two terms 'Hindu Tattva", which literally mean "Hindu Principles".
Hindutva is a stridently assertive rational-humanist line of reasoning. At the level of practice, the Hindutva outlook boils down to upholding righteousness (Sat-guna) and fighting ignoble attitudes (Dur-guna). Taking poetic license, we can describe the practitioners of this outlook as "Heenam Naashaayati iti Hinduhu" (Those who uphold righteousness and fight ignobleness are Hindus).
