As it is explained time to time by many saints that :
यद्यपि सकल गुरु पूज्य हैं, निज निज और अशेष।
तद्यपि मोक्ष प्रद परम गुरु, हैं जग माहीं विशेष
Although, all worldly gurus are venerable. All are sacred whether personal or endless others. But the Complete Guru who can lead you to moksha is exceptional in this world.
शोधी समान ना दाति
हरिजन समान ना जाति
जिन मानुष से देवता किया, करत ना लागी देर
गुरु गोविन्द दोनों खड़े, काके लागूं पांव
बलिहारी गुरु आपने, जिने गोविन्द दियो मिलाय
This couplet shows the disciple in the state of indecisiveness and dilemma, but later he figured it out. He was thinking that to whom he should greet first because both Guru and God are in front of him. Then he realized that he should first greet the Guru because, through Him, he can meet God.
राम नाम के पटतरे, देने को कछु नाहिं
क्या लै गुरु खुश होय, हौंस रहे मन माहिं
Guru has blessed his disciple with holy Naam, in generic it is called Ram Naam. Now the disciple is again in the confusion that there is nothing in this world to pay in return of holy Naam. He has a strong desire to know about the offering by which he can please his Master.
गुरु,गोविन्द तो एक है, दूसरा सब आकार
आपा मेट जीवित मरे, तो पाया करतार
Basically, Guru and God are one, There is the only bodily difference. In devotion, a devotee should have the same sentiments for both Guru and God. No duality is acceptable. Seekers should be free of ego. This way they can lead to the Ultimate.
सतगुरु सचा सुरिवां, शब्द जो बाह्या एक
लागत ही मैं मिट गई, पड़ा कलेजे छेक
This couplet tells us that Satguru is a true warrior. He hit me with word and within no time, my ego vanished. There is restlessness as disciple wants to meet God as soon as possible. He has now an urge to know about the secrets of life and death and even beyond that.
The above couplet is again highlighting the importance of having a Guru in life. It has been stressed that knowledge, salvation, the truth of life and death can not be acquired without a true master. A guru can only obliterate the imperfections of disciples.
गुरु समान दाता नहीं, याचक शिष्य समान
तीन लोक की सम्पदा, सो गुरु दीन्हि दान
There is no one as generous as the guru and solicitor like a disciple. Guru has gifted the estate of all three worlds ( Swarg, Patal and Prithvilok) to his disciple. Lord Kabira said in His literature that value of one mantra of Satnam is equal to the estate of three worlds ( Swarg, Patal and Prithvilok).
वह लोहा कंचन करे, येह कर ले महंत
As it is rightly said,
सात समुंदर की मसि करूं, लेखनी सब वनराय सब धरती कागज करूं, गुरु गुण लिखा ना जाये
