Six Systems of Vedic Philosophy

A list of six systems or ṣaḍdarśanas (also spelled Sad Darshan) consider Vedas as a reliable source of knowledge and an authoritative source.    Nyaya, Vaisheshika, Samkhya, Yoga, Mimāṃsā and Vedanta schools of Hinduism, and they are classified as the āstika schools:

1. Nyāyá, the school of logic http://freeglobaluniversity.blogspot.com/search/label/Gau
2. Vaiśeṣika, the atomist school http://freeglobaluniversity.blogspot.com/search/label/Atom
3. Sāṃkhya, the enumeration school http://freeglobaluniversity.blogspot.com/search/label/Cosmo
4. Yoga, the school of Patañjali http://freeglobaluniversity.blogspot.com/search/label/Patanjali
5. Mimāṃsā, tradition of Vedic exegesis http://freeglobaluniversity.blogspot.com/search/label/Karma
6. Vedanta Upaniṣhad https://freeglobaluniversity.blogspot.com/search/label/VedantaUpanishad

These are often coupled into three groups for both historical and conceptual reasons: Nyāyá-Vaiśeṣika, Sāṃkhya-Yoga, and Mimāṃsā-Vedanta.
