Ut means

Nectar of Instruction
One should not accept a spiritual master without following his instructions. Nor should one accept a spiritual master just to make a fashionable show of spiritual life. One must be jijñāsu, very much inquisitive to learn from the bona fide spiritual master. The inquiries one makes should strictly pertain to transcendental science (jijñāsuḥ śreya uttamam). The word uttamam refers to that which is above material knowledge. Tama means "the darkness of this material world," and ut means "transcendental." Generally people are very interested in inquiring about mundane subject matters, but when one has lost such interest and is simply interested in transcendental subject matters, he is quite fit for being initiated. When one is actually initiated by the bona fide spiritual master and when he seriously engages in the service of the Lord, he should be accepted as a madhyama-adhikārī.
