Shiva Swarodaya

Shiva Swarodaya is an ancient Sanskrit tantric text. A comment and translation termed as swara yoga has been made by Satyananda Saraswati in 1983. It is also termed "Phonetical astrology": the "sound of one's own breath" and is written as a conversation between Shiva and Parvati. This ancient scripture has 395 sutras.

Introduction
The script starts with the conversation between Parvati and Shiva, where Shiva starts introducing the scripts and explaining about the need for maintaining secrecy and also stating the astrological value of the text.

Its fundamental application is to realize the breath as being the medium of cosmic life force, through practising "Swara Yoga" (special mode of analysis & practising of breath). According to Mukti Bodhananda, the book enables us to understand nature of breath and its influence on the body as different modes of breathing leads to different types of actions; physical, mental and spiritual. Guruji Prem Nirmal says Swara yoga is an ancient science that correlates the breath with the sun, moon and the five elements, helping us to control moods, heal ailments and be attuned to the cosmic rhythm.

Introduction to swaras and their effects
According to Mukti Bodhananda finds, the second part introduces types of swaras arising out of Nadis, here three kind of swaras are said to be present. and each results of swaras are also noted here. Swarodaya Yoga' has three types of breathing systems - Ida (Inhaling & exhaling from our left side of the nostrils), Pingla (inhaling & exhaling from our right side of the nostrils) and Sushmana (inhaling & exhaling from both sides of the nostrils). We mostly breathe in & out from either Ida or Pingla but sometimes we breathe from both the nostrils Nadis.

Vata, Pitta and Kapha Doshas (imbalance) cause diseases and these can be balanced through Swara Yoga.

Recommended deeds during particular flow of swaras
Satyananda Saraswati implies each of the swaras mentioned in the book are suitable for very specific matching activities.

There are three modes of breathing, viz, flow from left nostril, flow from right nostril & flow from both the nostrils. The last mode is generally for a short duration when breathing switches from left to right & vice versa. Mode of breathing can be checked by examining air flow while exhaling.
