Darshana Upanishad
[1][6] The text presents classical Yoga similar to the Patanjali's Yogasutras-style format in a sequential ascending eight yogic stages, but unlike Yogasutras, the Darshana Upanishad includes kundalini concepts.[7] The ultimate goal of Yoga, states the Upanishad, is self-knowledge and realizing the identity of one's Self (Atman) with the Universal Reality (Brahman).[9] The text enunciates esoteric theories comparing the human body and blood veins with the terrestrial features of the earth such as river channels with their sacred fjords.[32][33] The axiology in the text includes a discussion of the value of Yamas and Niyamas,[34] such as non-violence, truthfulness, compassion, abstinence from anger, temperance in food (Mitahara), among others.[35][4] The text details yogic postures such as Svastikasana, Gomukhasana, Padmasana, Virasana, Simhasana, Bhadrasana, Muktasana, Mayurasana and Sukhasana.
