Māndukya 4.01
amātraś caturtho'vyavahāryaḥ। prapañcopaśamaḥ śivo'dvaitaḥ oṅkāraḥ। ātmaiva saṃviśaty ātmanā''tmānaṃ ya evaṃ veda ॥1॥
The fourth state, which is without measure, beyond expression, the cessation of all manifestation, auspicious, without wrong knowledge, is Omkara. The being who knows Ātmān thus, alone enters the Ātmān, by the grace of Ātmān.
Bhāshya 4.01
To show that the state of being beyond worldly dealings, that is equanimous, is possible here, it is again stated, 'avyavahāryaḥ', beyond expression, i.e. the state of being beyond worldly dealings, etc.
atraiva bhūtvā anyābhimānaṃ tyaktvā paramātmanaiva paramātmānaṃ praviśati upāsakaḥ। avyavahāryatvādikam atra samam iti darśayituṃ punar apy uktaṃ avyavahāryatvādikam ॥1॥
Right here, having become, the worshipper, having abandoned the sense of being other, becoming one with the Supreme Ātmān, he enters the Supreme Ātmān. To show that the state of being beyond worldly dealings, that is equanimous, is possible here, it is again stated, 'avyavahāryaḥ', beyond expression, i.e. the state of being beyond worldly dealings, etc.
