Māndukya 3.08

अकारो नयते विश्वमुकारश्चापि तैजसम्। मकारश्च पुनः प्राज्ञं नामात्रे विद्यतेऽगतिरिति ॥८॥

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)

प्रतिदिवसं विभाग एकीभावश्च विद्यते विश्वादीनाम् । तुरीयस्य तन्न विद्यत इत्यमात्रः। विश्वादीनां व्यवहारकारणत्वं विद्यते तुरीयस्य तन्न विद्यते इत्यतो गम्यत्वमपि नास्तीत्याशङ्कां निवारयति – 'अगतिर्न विद्यते' इति। आत्मानं संविशति इति गतिवचनात् ।

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".

"आदिमत्त्वेन सामान्यमुपास्येन भवेदिति।"

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

इति च।

- stated thus as well.

"आदिमत्त्वादिसामान्यं तुल्यं मोक्षोपभोग्यतः। अमात्रत्वं तुरीयस्याप्यविभागाद्दिने दिने॥"

"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."

इत्यात्मसंहितायाम् ॥

- stated thus in the Ātma-Saṃhitā.

॥ इति तृतीयखण्डः ॥

Thus ends the third section.
