The central channel stands in the middle, slender as the fibre in a lotus stalk; when it is meditated on as the Goddess whose nature is the inner sky, through her the God shines forth.

Commentary
Singh: meditate on the inner vacuity of the medial channel, which he identifies as the suṣumnā; the verse itself says only 'in the middle'.
How to sit with it
Rest awareness on one continuous slender channel through the middle of the body, fine as a lotus-stalk fibre, and feel its inside as open space rather than as a muscle to grip. No forcing of breath or effort.
Where attention rests
A slender channel through the middle of the body, sensed as open inner space
The quiet of that inner space
Not a body shape. The map is one very fine channel running through the middle of the body, felt as open inner space rather than as something to grip.
Breath
Equal four-count breath if counting helps, otherwise natural. No forced hold.
The counts are an optional school pacing aid, not part of the verse. Hold is always 0: this school never adds a deliberate breath-hold.
Any steady, comfortable position (school addition)
Any steady, comfortable position: sitting on a chair, sitting on the floor with support under the hips, or lying on the back. Standing or walking slowly is also acceptable when that is easier. Choose the position in which the body needs the least effort.
School addition. Verse 35 does not prescribe a body position. The seat is a convenience so the dharana can be practised; it is not part of the technique and makes no claim of tradition.
Safety
Pain is information. Pause, regress, or exit. Never push through sharp pain.
General practice caution only; not medical advice. If the image brings strong sensations or agitation, open the eyes and feel the whole body resting on the floor. If anything feels distressing (dizziness, agitation, strong emotion), stop, open the eyes and rest attention on the feet and the floor.
This door needs no particular posture: sit on a chair, sit on the floor with support, or lie down. Eyes may stay open.
Honesty
Door 012 follows Vijñāna Bhairava Tantra dharana 12 (verse 35) in Jaideva Singh's numbering. The door-to-dharana index is a School of 112 Doorways teaching device. Singh's sequence is one edition's count, not an ancient one-to-one canon. The seat, counts, reaction and beat scripts are school additions.
Door index = Jaideva Singh dharana number: Door 012 is dharana 12, verse 35. Other editions number differently (see dharana.numbering_variants).
The seat, breath counts, reaction metaphor, attention-map drawing and beat scripts are school devices, not part of the verse.
The English is a school paraphrase, not a quotation from any translator.
No medical claims. Reaction names are metaphors, not biochemistry.

The eight beats (spoken script)
Name the door. This is Door 012: space within the central channel. Vijñāna Bhairava Tantra dharana 12, verse 35.
Geometry. No shape to make. Any easy seat, or lie down. The map is one fine channel through the middle of the body.
Orientation. Body supported. Eyes closed or lowered. Orient to the exact middle.
Breath. Natural breath, or four in, four out. No forced hold.
Attention. Feel a channel as fine as a lotus fibre through the centre. Sense its inside as open space.
Reaction cue. School image: a crowded body-sense thins into one open channel. Metaphor only.
Adiyogi thread. Verse 35: the central channel, fine as a lotus fibre, meditated on as the Goddess of inner sky; through her the God shines. Space, not force.
Exit / integrate. Let the channel go. Feel the whole body again. Open the eyes.
