Sivasvarodhayatantra

Sivasvarodaya is a little book mainly dealing with predictions and right action based upon prāna's flow in the three main nadis. It has pretty obvious Tantric leanings. The tranlasation I have is by Ram Kumar Rai, published in 1997 (second edition) by Prachya Prakashan. The translator unfortunately makes no reference to the origins of the text, and from the text its hard (for me) to make any sort of guess about when and where it came from.

Sample below:

57. The left nādī Idā is nectar-like and supports the entire world. The right nādī Pingalā always creates the entire world.

58. The nādī in the middle is cruel and inauspicious for all occasions; while the left Nādī is always auspicious and bestows

      fructification of all actions.

59. The left nādī is auspicious at the time of proceeding for a work while the right is auspicious on the return. Therefore, one

      should always consider the Moon as even and virtuous and the Sun as

uneven and non-virtuous.

60. The Moon is a female. The Sun is a Male. The complexion of the Moon is fair and that of the Sun dark. When the Moon

      nādī is flowing then good and amiable works should be undertaken.

61. When the Sun nādī is flowing then cruel and daring works should be undertaken. When Susumnā is flowing then amorous,

     sexual, and such acts which lead to emancipation should be undertaken.
