Mantras dedicated to the Guru

गुरौ न प्राप्यते यत्तन्नान्यत्रापि हि लभ्यते।
गुरुप्रसादात सर्वं तु प्राप्नोत्येव न संशयः॥

gurau na prāpyate yattannānyatrāpi hi labhyate।
guruprasādāta sarvaṃ tu prāpnotyeva na saṃśayaḥ॥

English translation:
Whatever is not obtained from the Guru, cannot be obtained from elsewhere.
With the grace of the Guru one indeed gets everything.

Guru Paduka Stotram

The text in IAST and in devanagari.
