तन्त्रसार (महामाहेश्वर अभिनवगुप्त - तन्त्रालोक का प्रामाणिक सार-संग्रह सटीक)

reflected unmeṣa. As syllables these three are ā, ī, ū.
From ū onward kriyāśakti begins to function. The former
three parāmarśas are of the characteristic of prakāśa. Hence
they are of the nature of the sun and the latter parāmarśas,
that is, the longer vowels are of the nature of soma with
the characteristic of rest.
When icchā and īśana become inclined towards activity,
or in other words, when activity enters them, it sets in
disturbance and causes a break in tranquility. Then icchā
and īśana are known as īśyṣamāna īśyamāna. In the one
light is predominant and in the other it is of the nature of
rest. They are known as ṛ, ṝ, ḷ, ḹ. As they are only śruti
(semitone) and sound like consonant sounds of ra and la,
they do not come under consonants proper. As they retain
the vowel and consonant sounds both, they are considered
as neuter.

anuttara give rise to different varṇas. The impelling force
of kriyāśakti terminates after giving rise to the varṇas like
e (ए), ai (ऐ), o (ओ) and au (औ) After that the inward move
begins to operate, as a result all the resultants are then put
to rest in anuttara. It is to be noted here that this anuttara
is different from anuttara akāra, the Supreme Bhairava. It
manifests as aṃ (अं) which is in essence pure consciousness.
From that anuttara visarga ( : ) occurs.
Visarga better known as visargaśakti, is the creative
force which not only operates but manifests herself as the
universe. She remains inseparably united with the Absolute
before the rise of kṣobha in it. The universe as we see it,
is the manifestation of light as indicated objects (vācya)
and the reflection of that light in its turn, stands for each of
