The greatness of Sanskrit language

The Sanskrit language or Sans‌kr̥taṁ dates back to the bronze age and it is the sacred language of Āstika  traditions. Vaidika or Vedic Sanskrit which was the language of Vedic texts later evolved into Laukika or classical Sanskrit. The Prākṛta or Prakrit languages were also related to Sanskrit and they were a later development.

During the early period, Sanskrit was mostly utilized  in  northern regions of India or Bhāratavarṣa and later it was utilized all over India and even beyond India as the Indian culture spread into wider regions. At its height, Sanskrit was utilized in a large area covering from Afghanistan to Indonesia. Through Buddhism, Sanskritic elements also reached many other regions such as Central Asia and East Asia.
Sanskrit or Sanskritic origin is also the single factor which unites and links all the diverse Indian religious and cultural traditions.

The corpus of  ancient Sanskrit literature  is huge and the ancient texts like four Veda Samhita-s, Āraṇyaka-s, Brāhmaṇa-s, Upaniṣad-s, Kalpa sūtra-s , Dharma śāstra-s and Smr̥ti-s , epics Rāmāyaṇa and Mahābhārata, Purāṇa-s and Upapurāṇa-s , Tāntric-Āgamic texts, Brahma sūtra, Mimamsa sūtra, Nyāya sūtra, Vaiśēṣika sūtra and numerous other works like Nāṭya-śāstra, Yoga sūtra, Kāma sūtra, Caraka Samhita, Suśruta Samhita etc would probably make the Sanskrit literature the largest ancient literature on the planet.

 It must also be noted that today we only posses Vedic texts from the surviving Śākha-s or branches of Vedic schools. Once, there existed more Vedic Śākha-s and the texts associated with the Śākha-s which are extinct today. So we can never underestimate the size of ancient Sanskrit corpus. The knowledge of Sanskrit would help one in reading all the surviving ancient texts, though it will take a lifetime to read all of them thoroughly.
