The Yogin hears mystic noises during his trance, which he refers to as Anahata sounds. It is a symbol of Nadis' purification. Some students can distinctly hear it with one hand, while others can hear it with both. There are both harsh and soft noises. Through the noisy to the soft, and from the subtle to the subtler, one must reflect. Beginners can only detect the sound with their ears closed. Even without shutting their ears, advanced students can focus on the Anahata message. Omkara Dhvani is another name for Anahata tone. They start from the Sushumna Nadi's Anahata center.
Place yourself in your normal Asana. Thumbs are used to close the ears. Through the ears, listen to and observe the internal vibration. You will become deaf to all external sounds as a result of the sound you hear from within. Close your eyes as well. You can hear a lot of noisy noises at the start of the session. Later on, they can be heard in a more subdued manner. The subconscious, having initially focused on a single tone, becomes permanently attached to it and immersed in it. The subconscious becomes insensitive to external stimuli, becoming one with the sound as milk becomes one with water, and then quickly consumed in Chidakasa. The Chitta, which is still immersed in the inner scent, does not long for sensual things, as it is bound by the sweet fragrance or Nada and has lost its flitting existence, just as the bee drinking honey alone does not care about the odour.
The sound emanating from Pranava Nada, which is Brahman, is effulgent in nature.
The subconscious becomes engrossed in it. The mind persists as long as there is tone, so when it stops, it enters the Turiya state. That is the highest level of government. It is the condition of Unmani. Constant emphasis on Nada absorbs both the consciousness and the Prana. The body resembles a log of wood, with no sensations of hot or cold, pleasure or sorrow. Different types of sounds (Anahata sounds) emanate from the heart.
There are ten types of nada that can be heard by the ears. The first is the sound of a bell; the second is ‘Chini-chini'; the third is the sound of a conch; the fourth is the sound of a lute; the fifth is the sound of cymbals; the sixth is the tune of a flute; the seventh is the tune of a flute; the eighth is the voice of a drum (Bheri); the ninth is the sound of a double-drum (Mridanga); and the tenth.
You can't begin to hear something right after you shut your ears. You should focus and keep your attention on one thing. It's possible that the sound you hear now isn't one you'll hear every day. However, all of the ten Anahata sounds can be heard.
Laya via Nada, Anahata is the sound mentioned above. In the same way, focus at the tip of the nose (Nasikagra Drishti), the area between the two eyebrows (Bhrumadhya Drishti), meditation on the five Tattvas, Soham Mantra, Aham Brahma Asmi, Tat Tvam Asi Mahavakyas, and other methods will affect Laya.
