A research journal with the evolutionary link of Rudra & Śiva across Veda Saṃhitās to Āraṇyakas and their synopsis in the Upaniṣhads of Rig/Ṛg, Yajur to Atharva Vedic Śākhās. Finally, how it all landed in the Itihāsas. The sources and topics listed below are a journey across the three dimensions in which the Rishis (Ṛṣi) divided the Vedic context: adhibhautika (physical); adhidaivika (Divinity/Deva); and ādhyātmika (Yogic union with cit). The sources and citations in our journey are:

Why is Rudra Pashupati? It meaning?
