Māndukyōpanishad Bhāshya

युञ्जीत प्रणवे चेतः प्रणवो ब्रह्म निर्भयम्। प्रणवे नित्ययुक्तस्य न भयं विद्यते क्वचित् ॥३॥

yuñjīta praṇave cetaḥ praṇavo brahma nirbhayam। praṇave nityayuktasya na bhayaṃ vidyate kvacit ॥3॥

[युञ्जीत (yuñjīta) - one should unite; (from root 'yuj', to join, unite; optative mood); प्रणवे (praṇave) - in the praṇava (sacred syllable Om); चेतः (cetaḥ) - the mind; (from 'cetas', mind, consciousness); प्रणवः (praṇavaḥ) - the praṇava (Om); ब्रह्म (brahma) - Brahman; (the Absolute, ultimate reality); निर्भयम् (nirbhayam) - fearless; (nir- prefix meaning 'without', bhaya meaning 'fear'); प्रणवे (praṇave) - in the praṇava (Om); नित्ययुक्तस्य (nityayuktasya) - of one who is always united; (nitya - always, yukta - joined, sa - of); न (na) - not; भयम् (bhayam) - fear; विद्यते (vidyate) - exists; (from root 'vid', to be, to exist); क्वचित् (kvacit) - anywhere; (at any time, at any place);]

One should unite the mind in the praṇava (Om); the praṇava is Brahman and is fearless. For one who is always united with the praṇava, there is never any fear anywhere.

बहुचित्रजगद्बहुधाकरणात् परशक्तिरनन्तगुणः परमः ।
सुखरूपममुष्य पदं परमं स्मरतस्तु भविष्यति तत्सततम् ॥
"The one who has created this variegated vast universe with varied forms has infinite power and is of infinite auspicious qualities. He certainly bestows the highest state of bliss to those who meditate on his ever happy essence." -Dwādasha stōtra 4.3
