The Krishna Yajur Veda Samhita exists today in various recensions, most importantly the Taittiriya Samhita and the Maitrayani Samhita. The Shukla Yajur Veda Samhita is preserved most prominently as the Vajasaneyi Samhita. See: Vedas. Yama: (Sanskrit) "The restrainer." Hindu God of death; oversees the processes of death transition, guiding the soul out of its present physical body. See: death.

yama-niyama: (Sanskrit) "Restraints-observances." The first two of the eight limbs of raja yoga, constituting Hinduism's fundamental ethical codes, the yamas and niyamas are the essential foundation for all spiritual progress. They are codified in numerous scriptures including the Shandilya and Varuha Upanishads, Hatha Yoga Pradipika by Gorakshanatha, the Tirumantiram of Tirumular and the Yoga Sutras of Patanjali.

All the above texts list ten yamas and ten niyamas, with the exception of Patanjali's classic work, which lists only five of each. The yamas are the ethical restraints; the niyamas are the religious practices. Because it is brief, the entire code can be easily memorized and reviewed daily by the spiritual aspirant. Here are the ten traditional yamas and ten niyamas. -- yamas: 1) ahimsa: "Noninjury." Not harming others by thought, word, or deed.
