Question

What are the six darsanas or philosophies mentioned in kularnava tantra which are known to be the six limbs of Shiva?

Answer 1

Six Schools of Indian Darshana's are as below:

1. Nyaya
2. Vaishesika
3. Purva Mimamsa
4. Samkhya
5. Yoga
6. Uttra Mimamsa

Here Uttra mimamsa is Upanishad (Vedic postulate) and Purva mimamsa is vedic text itself (yaga and other vedic literature). Nyaya is Logic which (madhva school of philosophy greatly emphasis) Nyaya Sudha, Nyayaamruta, chandrika, Parimala. Samkhya is numerology and their relation to vedic philosophy. There 2 philosophy here one is asthikia propopunded by Kapila Avatara, and another is nirishwara sankhya propounded by Kapila rishi. All know about Panthajali and Hatha yoga. only left is Vaishesikia that is metaphysics its about how the universe is composed off atomic nature.

There were other schools of taughts like Charvaka, Pashupatha, Jaina, Buddha All rejects Vedic authority. Like Nasthika Samkhya. So they are not considered.

Answer 2

As per Parshurama Kalpa Sutras, By Dr. Param Hans Mishra, Bhagwan Shiva himself created Six Darshanas; they are:

1. Shaiva Darshana
2. Vaishnava Darshana
3. Bramha Darshana
4. Saur Darshana
5. Shakta Darshana
6. Baudhdha Darshana

Since the book is in Hindi, used Google Translator for English translation:

Apart from these, six darshans are also Bhagavatpravart. By whom real darshana happens, it is called darshana. These six are considered - 1. Shaivadarshan, 2. Vaishnavadarshan, 3. Brahmadarshan, 4. Sauradarshan, 5. Shaktadarshan and 6. Bauddhadarshana. By establishing Panini, Vyasa, etc., Paramashivabhattaraka changed all the disciplines, scriptures and philosophies in this way. In this, he did not have to do any Ayas, but it was accomplished by Lilah.
