INTRODUCTION
 
Svarodya- vijñāna, is the science of prediction about the
breather's health, his future and auspicious, or inauspicious
possibilities for him in various walks of life through the rise
of breathing in one or the other nostrils. Due to a causal rela-
tionship the Pnāņa-vāyu and the Manas are one. Therefore,
by conquering the Prāṇa-vāyu one can conquer the Mahiprā-
na and the Manas. Achievement of the conquest of the Mahā.-
prāṇa (Mahāprāṇa-jaya) and Manas (Manojaya), and the
knowledge of the Essence through this conquest is called
Svarodaya. Although, due to the diversity of the Sūkṣma-sakti
(Subtle Power) the activities and fruits of Svarodaya are
infinite, yet a little of it is being described here for the bene-
fit of the Yogis. There is no better brother than Svara-vijñāna
or better wealth than Svara-jñāna, or better secret than
Svara-jñana. Destruction of enemies, meeting with members of
the fraternity, achievement of wealth, fame and bride, inter-
view with king, and even subjugation of the kings, all these
can be achieved through Svaravijñāna.
 
All the Purāṇas, Smṛtis, Vedāngas and Tantras have
originated from Svara. Therefore, there is no other better
friend in this world than the Svara-vijñāna. This science of
Svarodaya is superior to all other sciences. Just as one needs
a torchlight in order to see the things in house, so for
self-enlightenment one needs the knowledge of Svarodaya.
 
Kinds of Vayus:-There are ten kinds of Vayus (Airs)
residing in the body, viz., Prāņa, Apāna, Samāna, Udāna,
Vyāna, Nāga, Kūrma, Kṛkara, Devadatta and Dhananjaya
(See VAYU). All these Vayus keep on roaming in the
various vessels of the body. A person adept in the science of
Svarodaya experiences the activities of these Väyus through
three most important Nadis-the Pingalā, Iḍā, and Suşumnā.
