Upavedas

Upavedas are four and they are Dhanurveda, Gandharvaveda, Ayurveda and Arthasastra. Some schools hold Sthapatyaveda as the fourth Upaveda instead of Arthasastra. Dhanurveda is the science of warfare. Gandharvaveda is the study if aesthetics and it speaks of all art-forms like music, dance, poetry, sculpture, and erotica. Ayurveda is the science of health and life. Arthasastra deals with public administration, governance, economy and polity. Sthapatya Veda is engineering and Architecture. All these sciences/arts are discussed not just from their technical perspective (though that is primarily done); these are seen as means to transcendence.
