Ancient Indic Philosophy always wished everyone to be joyous and free from mental illness and implored for an all-inclusive holistic development on the planet for amity and harmony in the 'Bhumi Sukta' of Atharva Veda.
The roots of what we refer to as the caste system today, Hinduism's chaturvarna or four varnas, can be traced to Purusha Sukta, "The Hymn of Man." It is believed by some scholars to be a late addition to the Rig Veda, the earliest example of Hinduism's Vedic literature dating somewhere between 1200-900 BCE.
Active imagination is prominent in the Vedic hymns, such as Sri Sukta. Subsequent texts such as Bhavanopanisad epitomize the internal ritual, where the mandala and the body of the deity correspond to the body of the aspirant.
These Puranas brought about certain coherence in their metaphysics also by identifying Sankhya conception of the Purusa with that of the Vedic concept of Purusa as enunciated in the Purusa Sukta, (who is also Visnu/ Narayana/Vasudeva, the pure existence) of the Rg Veda.
