Māndukya 3.08

akāro nayate viśvam ukāraś cāpi taijasam। makāraś ca punaḥ prājñaṃ nāmātre vidyate'gatir iti ॥8॥

The letter 'A' represents the waking state and the universe, 'U' represents the dream state and the luminous aspect, and 'M' represents the deep sleep state; By the 'amatra', i.e. without measure, i.e. the turiya or fourth state, non-movement does not come to light, thus.

Bhāshya 3.08

Every day, division and unity are present for Viśva and the other forms, but for Turīya, these do not exist, hence it is called amātra, without measure. For Viśva and the others, there is a causal role in empirical dealings, but for Turīya, this is absent; therefore, even knowability is not present — this doubt is dispelled by stating - "non-movement also does not come to light". Primordial nature and such generality, i.e. universality inhering in many, are equally applicable to liberation and the enjoyment that results. The immeasurability of the fourth state is due to its indivisibility, that remains day after day.
(नामात्रे विद्यतेऽगतिः = न अमात्रे विद्यते अगतिः = अमात्रे विद्यते न अगतिः)

pratidivasaṃ vibhāga ekībhāvaśca vidyate viśvādīnām । turīyasya tanna vidyata ityāmātraḥ। viśvādīnāṃ vyavahārakāraṇatvaṃ vidyate turīyasya tanna vidyate ityato gamyatvamapi nāstītyāśaṅkāṃ nivārayati – 'agatirna vidyate' iti। ātmānaṃ saṃviśati iti gativacanāt ।

Every day, division and unity are present for Viśva and the other forms, but for Turīya, these do not exist; hence it is called amātra (without measure). For Viśva and the others, there is a causal role in empirical dealings, but for Turīya, this is absent; therefore, even knowability is not present — this doubt is dispelled by stating - "non-movement also does not come to light". The proverb regarding movement in context is "It enters the Ātmān".

"ādimattvena sāmānyam upāsyena bhaved iti."

"The quality of 'ādimattva', i.e. the primordial nature, is-ness, reality of the universe - is realized by worshiping the universality inhering in many."

iti ca।

- stated thus as well.

"ādimattvādisāmānyaṃ tulyaṃ mokṣopabhogyataḥ। amātratvaṃ turīyasyāpyavibhāgāddine dine॥"

"Primordial nature and such generality, i.e. universality inhering in many, are equally applicable to liberation and the enjoyment that results. The immeasurability of the fourth state is due to its indivisibility, that remains day after day."

ityātmasaṃhitāyām ॥

- stated thus in the Ātma-Saṃhitā.

॥ iti tṛtīya-khaṇḍaḥ ॥

Thus ends the third section.
