Naasti buddhir ayuktasya na chaayuktasya bhaavanaa
Na chaabhaavayatah shaantir ashaantasya kutah sukham

Sanskrit: 

नास्ति बुद्धिर् अयुक्तस्य न चायुक्तस्य भावना
न चाभावयतः शान्तिर् अशान्तस्य कुतो शुखम्

Oriya: 

ନାସ୍ତି ବୁଦ୍ଧିର୍ ଅଯୁକ୍ତସ୍ୟ ନ ଚା ଯୁକ୍ତସ୍ୟ ଭାବନା
ନ ଚାଭାବୟତଃ ଶାନ୍ତିର୍ ଅଶାନ୍ତସ୍ୟ କୁତୋ ଶୁଖମ୍

Selected word meaning:
naa asti - there cannot be, buddhih - transcendental or spiritual intelligence (knowledge of Self), ayuktasya - of one who is devoid of transcendental intelligence, na - neither, cha - and, ayuktasya - of one who is devoid of transcendental intelligence, bhaavanaa - meditation (a steady mind), na - neither, cha - and, abhaavayatah - one whose mind is not fixed, shaantih - peace, ashaantasya - of the one devoid of peace, kutah - where is, sukham - happiness

Translation:
There is no transcendental knowledge for an unsteady mind, and to the one with unsteady mind no meditation is possible, and there can be no peace for the un-meditative, and to the one who is devoid of peace, how can there be happiness?
