In plain words
The Guru is Brahman directly present. Mumukṣus—those who long for liberation—serve and revere the Guru. A grateful person with Viveka—discernment—never causes the Guru distress.
Close to the Sanskrit
The Guru is directly Brahman itself; the Guru is to be served and revered by Mumukṣus—seekers of liberation. A grateful person endowed with Viveka—discernment—should never cause the Guru distress.
