In the initial stages it is stressed that these teachings are primarily for the Brahmacaris, those who are free from desires, devoted to his/her guru and always contemplates this Hamsa who pervades everywhere. This Hamsa is said to be the essence of all there is and a person who comes to know this will not die.

No specific Pranayama exercises are referred to, apart from contracting the anus and raising the internal breath up through the chakras. Once having reached the Ajnya (between the eyebrows), one should contemplate the formless aspect of the Atman.

This Hamsa, which has Buddhi as it’s main vehicle, has eight vrrtis and depending on where it rests in the inner lotus of the heart it has certain personality traits as referred to in the Dhyanabindu Upanishad. When the Hamsa is able to rest in the center, it may become absorbed in the Nada (divine sound) beyond speech and mind. It is like pure crystal and extends from the base of the spine to the crown of the head.

What then follows is a traditional mantra instruction where a mantra is classified into six parts that gives the rishi (seer), meter, presiding deity, seed, shakti (power) and bolt of the mantra. Here ‘Ham’ is the seed, ‘Sa’ is the shakti, and the bold that unlocks it is  “So’ ham”. According to the text, due to the coming and going of the breath within the body, this mantra is pronounced involuntarily 21,600 times in a day and night. As one becomes more receptive to this sound the luminous essence of the Hamsa may illuminate ones understanding. More detailed instructions are given regarding, the head, feet and two wings of this inner swan, and ultimately it is all for the purpose of contemplating this Hamsa as the inmost essence of ones heart. As ones inner receptivity increases and one attains a more elevated state of mind, one may eventually learn to distinguish between different types of sound within the spinal column. As this upward movement occurs there is also the equivalent effect within the body illustrated in the table beneath:

 

Stages	The sounds of Nada	Effects within the body
1	Trinkle	Vibration
2	Trianlge	Slight break
3	Bell	Piercing
4	Counch	Head shakes
5	Lute	Palate produces saliva
6	Cymbals	Nectar is tasted
7	Flute	Knowledge of what has been concealed arises.
8	Drum	Distant sound is heard.
9	Double drum	The Divine eye is opened.
10	Cloud (Thunder)	Attains union with Paramatman

 

In the highest state there is a complete absorption in Brahman. The mind looses its separate identity due to the destructions of all thought and fancy (sa¶kalpas and vikalpas), all sins and virtues are burnt away and what remains is the effulgent light of the essence of self. This (according to this texts), is the highest teachings of the Veda. To attain the immaculate, eternal, stainless inner essence of OM.
