Hi,
" Ikna nadi na bedi na giya rasu, rasu, kasu na janati,
Ikna sidhi na budhi na agli sar, akkhar ka beheo na lahanti,
Nanak te nar asli khar, ji binu gun garabu karanti. "
"There are those who are cultured neither
in philosophy, nor in scripture, not have developed proper taste for music. And likewise, there are those who are unacquainted with aesthetics and arts. They have neither a trained character, nor disciplined intellect, and as such, they are devoid of true learning, so much so that the true significance of accumulated human wisdom is outside their sphere of interest. Such people, says Nanak, are true animals for they strut as human beings without the qualifications of human beings."
— Guru Granth, 1, 1411 (Translation by Sardar Kapur Singh)
