Hindu society has grown and shaped itself in the vision of Vyasa and Valmiki, Manu and Yajnavalkya, Narada and Vasistha, and a hundred other exponents of Sanãtana Dharma in all its dimensions and dynamics. Hindu society has been inspired through the ages by such mighty šãtras as the Vedas, the Upanishads, the Gita, the Jainagama, the Tripitaka, the various Yogasastras, the Vani of Siddhas and Sants, and the devotional outpourings of Alvars and Nayanars. Hindu society has been defended, during its days of distress, by such high-souled heroes as Chandragupta, Skandagupta, Vikramaditya, Yasodharman, Bapa Rawal, Jayapala, Bhojadeva, Prithiviraj, Prataparudra, Vir Pandya, Harihara and Rana Sanga. Hindu society has fought a long-drawn-out struggle for freedom against Islamic invaders under the leadership of such veterans as Maharana Pratap, Shivaji, Maharaja Surajmal, Banda Bairagi, Lokmanya Tilak, Veer Savarkar, Mahatma Gandhi, and Sardar Patel.
