Sankaracarya's Vivekachudamani 578

गुरुरेव सदानन्दसिन्धौ निर्मग्नमानसः ।

पावयन्वसुधां सर्वाण्विचचार निरन्तरः ॥

gurureva sadānandasindhau nirmagnamānasaḥ |

pāvayanvasudhāṃ sarvāṇvicacāra nirantaraḥ |

(Sankaracarya's Vivekachudamani 578)

And the Teacher, his mind immersed in the ocean of eternal Bliss, forever wandered about, verily blessing the whole world.

Blessed disciple liberated. A bonafide guru always 24/7 in the thought of Lord Sri Mukunda, he never wastes a single second in enjoying the material life. The concern of a real guru to liberate(Mukti) all his students. Gurus always come to this earth to bring all suffering souls to the Lotus Feet of the Lord. A guru will not be busy with doing black magic, politicking, and putting himself in the center of enjoyment. Today every one of us is getting cheated by bogus gurus because we don't accept the true teaching which directs us to surrender to the Lord. Most of like to have fake gurus who offer material benefits. This life is not mending for material benefits. Please don't waste a single second in this world, please learn about the Supreme Lord from great Acarya like Sankaracarya, Ramanujacarya, and Madhvacarya. They are still living with us. It's just we are not approaching them.
