When you attend to that sound,
does attention narrow and concentrate,
or does it expand and become spacious?

When attention narrows and concentration intensifies, it means:

You are using nāda as an object of dhāraṇā (focused concentration).

This is valid.
But it is only the first phase.

Let me explain carefully.

1️⃣ Narrowing Phase (Concentration Mode)

In this stage:

• Attention locks onto the sound.
• Peripheral awareness reduces.
• Mind becomes one-pointed.
• Cognitive chatter decreases.

This strengthens ekāgratā (one-pointedness).

This corresponds to classical Laya Yoga instructions:

Fix mind on nāda until other thoughts subside.

This stage builds stability.

But there is a subtle risk.

If attention becomes too tight,
effort increases,
subtle strain enters.

That prevents deeper laya.

2️⃣ The Transition That Must Happen

After concentration stabilizes,
there should be a shift:

Instead of:
"I am focusing on the sound"

It becomes:
"The sound is simply present"

Then gradually:
"The sound and awareness are not separate"

Then:
"Even sound dissolves"

If narrowing continues indefinitely,
you remain in refined concentration,
not dissolution.

3️⃣ Why Your Attention Narrows

Because your system is disciplined.

You have strong inward orientation.
So the mind naturally grips subtle object firmly.

This is a yogic temperament.

But now refinement is needed.

4️⃣ What Should Happen Next?

Instead of tightening around nāda,
try this subtle experiment:

Do not move toward the sound.

Let the sound appear inside awareness.

Do not contract attention.

Let awareness remain wide,
and allow the sound to float in it.

If done correctly:

Concentration softens.
Presence expands.
Effort reduces.
Sound becomes subtler.

Eventually,
attention is no longer narrow.
It becomes vast.

This is transition from dhāraṇā → laya.

5️⃣ Final Subtle Point

When attention narrows:
mind is active in refined way.

When awareness expands:
mind is dissolving.

Nāda is bridge between the two.
