For one who repeats the letter 'a' without the nasal dot (bindu) and without the out-breathed 'ḥ' (visarga), O Goddess, a great flood of knowledge, the Supreme Lord, rises suddenly.
School paraphrase drawing on Jaideva Singh (1979), Christopher Wallis and Bettina Bäumer (as printed in Wallis's concordance); not a quotation.
Commentary
Singh: 'a' with bindu would be 'aṃ' (an in-breath) and with visarga 'aḥ' (an out-breath); without either, it implies sounding 'a' in a state of breath retention, according to the commentary. Lakshmanjoo instead reads the commentary's 'retention' as a posture of the mouth (cakita mudrā: mouth wide open, tongue drawn back), so that 'a' can only be sounded mentally. 'A' is chosen as the first letter, source of all others, the symbol of the absolute (anuttara) and of perfect I-consciousness (aham).
How to sit with it
Sound a soft, plain 'a' (as in 'father'), without closing it into a hum and without letting it end in a breathy 'h'. Repeat it gently, aloud or in the mind. Rest in the open quality of the sound.
Where attention rests
The plain vowel 'a', without a closing hum or a breathy ending
The open, wordless quality of the sound
Not a body shape. The map is one open vowel, 'a', sounded without closing into a hum and without trailing off into a breath.
Breath
Natural breath. Sound a soft, plain 'a' on part of an out-breath, or sound it in the mind only. 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 90 does not specify 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. The commentary's breath-retention reading is not taught; keep breathing naturally between sounds. 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 067 follows Vijñāna Bhairava Tantra dharana 67 (verse 90) 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 067 is dharana 67, verse 90. 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.

Name the door. This is Door 067: sounding the plain letter 'a'. Vijñāna Bhairava Tantra dharana 67, verse 90.
Geometry. No shape to make. Sit or lie down. The map is one open vowel: 'a', with no hum and no breathy ending.
Orientation. Let the floor or the chair carry you. Eyes closed or soft.
Breath. Natural breath. Sound 'a' on part of an out-breath, or silently. No hold.
Attention. Sound a soft, plain 'a'. Do not close it, do not let it trail off. Repeat, aloud or in the mind. Rest in its openness.
Reaction cue. School image: a sound held open. A metaphor, not medicine.
Adiyogi thread. Verse 90: repeating 'a' without bindu or visarga, a great flood of knowledge, the Supreme Lord, rises suddenly. No breath-holding here.
Exit / integrate. Drop the exercise. Notice the room: its sounds, its light. Carry the quiet into what comes next.
