Subhashitams from Kularnava Tantra

प्रेरकः सूचकश्चैव वाचको दर्शकस्तथा। शिक्षकः बोधकश्चैव षडेते गुरवः स्मृताः॥

prerakaḥ sūcakaścaiva vācako darśakastathā । śikṣakaḥ bodhakaścaiva ṣaḍete guravaḥ smṛtāḥ ॥

The Kularnava Tantra describes a guru through six roles: one who inspires, indicates, explains, demonstrates, teaches, and awakens understanding.
