20 srotriyo-avrijino-akaamahato

श्रोत्रियोऽवृजिनोऽकामहतो यो ब्रह्मवित्तमः ।
ब्रह्मण्युपरतः शान्तो निरिन्धन इवानलः
अहेतुकदयासिन्धुर्बन्धुरानमतां सताम्
विवेकचूडामणि: ३३

śrotriyo’vṛjino’kāmahato yo brahmavittamaḥ |
brahmaṇyuparataḥ śānto nirindhana ivānalaḥ
ahetukadayāsindhur-bandhur-ānamatāṃ satām
Vivekacūḍāmaṇi: 33

He who is well-versed in scriptures, who is taint-less and pure, who is free from desires, who is a Knower of Brahman of the highest order, who has withdrawn into the Supreme, who is peaceful like fire that is devoid of fuel, who is an ocean of mercy that needs no cause for its expression, and he who is a friend to those good people who surrender to him.

Worshiping such a Guru with devotion, and when that Guru is pleased with one’s surrender, humility and service, approaching him, one should ask about all that is to be known.
