श्रीसद्गुरुरुवाच
गुरोरनुग्रहेणैव लभ्यते हरिदर्शनम् |
तस्माद्गुरुं दीनबन्धुं पूजयेत्सर्वथा नरः ||
गुरुरेव हरिः सक्षाद्धरिरेव गुरुः परः |
एवं ह्यनन्यभावेन भजेदाचार्यपुङ्गवम् ||
प्राप्तुमिच्छति यो विष्णुं भवबन्धविमोचनम् |
दृढविक्ष्वाससंयुक्तो गुरुमेव भजेत्सदा ||
गुरुर्माता गुरुस्तातो गुरुर्बन्धुर्गुरुः सखा |
गुरुरेव परम् दैवं गुरुरेव परा गतिः ||
घोरे संसारकान्तारे भ्रमतामविवेकिनाम् |
सन्मार्गदर्शको बन्धुर्गुरुरेव परा गतिः ||
Shri Sadguru said
Once can receive the great boon of Hari darshan only with the blessings of the guru. One should worship the guru who is the refuge of the meek and simple. Guru is Lord Hari incarnate. Lord Almighty Hari is to be identified with guru. Hence one should worship his guru in the same way as he worships Lord Hari. One who wants to attain Lord Vishnu who is the ford finder of the ocean of samsara, should worship guru always with unflinching faith. Guru is the mother; guru is the father; guru is the kinsman; guru is the friend; guru is the Supreme God; guru is the final refuge of one. Guru is the ultimate refuge, for he is the path finder for all disillusioned men who wander in the fiercest forest of samsara.
