Gurbani mentions many times to do Guru Sahib’s Seva or Akaal Purakh’s Seva. Countless Gurbani pangtis refer to the benefits of doing Guru Sahib’s Seva, reminding us repeatedly to do Guru Sahib’s Seva. The question is what is Guru Sahib’s Seva, how can we do Guru Sahib’s Seva? Is Guru Sahib’s Seva the physical act of doing Seva such as Chaur Seva? How can we spend 24 hours engrossed in Chaur Seva, how can we spend our entire lives only doing Chaur Seva? As Gurbani tells us to serve the Guru with every breath. So, what does Gurbani mean when it says to serve Guru Sahib?
Guru Sahib has answered this question in Gurbani Himself.
ਗੁਰ ਕੀ ਸੇਵਾ ਕਰਿ ਪਿਰਾ ਜੀਉ ਹਰਿ ਨਾਮੁ ਧਿਆਏ ॥(Ang, 246)
In this Gurbani, Guru Sahib gives us an Updesh (instruction), the line says My dear soul, do Seva of Guru Sahib by engrossing yourself in Naam Simran. This next line makes it clear as well, Seva of Guru Sahib is the act of doing Naam Simran. ਧੁਰ ਕੀ ਸੇਵਾ ਰਾਮੁ ਰਵੀਜੈ ॥ (Ang, 905) This line removes all doubts on what Guru Sahib’s Seva is. Guru Sahib tell us to do the Seva we received from the beginning, from our birth, this is the Seva of Naam Simran, this is True Seva.
The following line Guru Sahib says it in even more simple words, it is as if Guru Sahib knew we would have lingering doubt, Guru Sahib rids us of that doubt in this line:
ਗੁਰ ਕੀ ਸੇਵਾ ਗੁਰ ਭਗਤਿ ਹੈ ਵਿਰਲਾ ਪਾਏ ਕੋਇ ॥1॥ ਰਹਾਉ ॥ (Ang, 66) Guru Sahib declares in this Shabad that Guru’s Seva is Bhagti! The only Seva of Guru Sahib is Naam Simran. If we do Naam Simran we are doing Seva of Guru Sahib. There is no other Seva of Guru Sahib.
When Gurbani tells us to do Seva of Guru Sahib, it means do Naam Simran. Now of course this does not mean we should not do Seva of Sri Guru Granth Sahib Jee by doing Chaur or other Sevas. We need to give as much Satkaar possible to Guru Sahib’s physical form, that is our duty.
