ਦੇਹ ਸਿਵਾ ਬਰੁ ਮੋਹਿ ਇਹੈ ਸੁਭ ਕਰਮਨ ਤੇ ਕਬਹੂੰ ਨ ਟਰੋਂ ॥O Shiva, give me this boon that I may not hesitate from performing good deeds.
ਨ ਡਰੋਂ ਅਰਿ ਸੋ ਜਬ ਜਾਇ ਲਰੋਂ ਨਿਸਚੈ ਕਰਿ ਅਪੁਨੀ ਜੀਤ ਕਰੋਂ ॥That I may not fear the enemy, when I go to fight and assuredly become victorious.
ਅਰੁ ਸਿਖ ਹੋਂ ਆਪਨੇ ਹੀ ਮਨ ਕੌ ਇਹ ਲਾਲਚ ਹਉ ਗੁਨ ਤਉ ਉਚਰੋਂ ॥And that I may instruct my mind to have the greed to ever utter Your Praises.
ਜਬ ਆਵ ਕੀ ਅਉਧ ਨਿਦਾਨ ਬਨੈ ਅਤਿ ਹੀ ਰਨ ਮੈ ਤਬ ਜੂਝ ਮਰੋਂ ॥੨੩੧॥That when the end of my life comes, that I may die fighting bravely in the battlefield.231.
See Sri Dasam Granth Sahib ji, Sri Chandi Charitra Sahib.
Shiv here is an attributative name for Akal Purakh. Bhai Balbir Singh ji was raised by Akali Baba Chet Singh in Buddha Dal, he did Kirtan at Darbar Sahib for 35 years. His brother was a Farla-dhari Nihang Singh, he says at 28: 50 in the following recording:
That Sikhs do not worship Shiva and that Shiva in this Shabad means Pure or Shubh. He quotes shabads from Guru Granth Sahib ji telling Sikhs not to worship deities but only the One Timeless Being. Then he talks about Indira Gandhi's death.
Is Shiv ji Mahakal?
There are many misconceptions about the term Mahakal. In actual fact it's gender is neutral e.g. it is not male or female. For example " In Sri dasam Granth sahib ji mahakhaal-kaalika aradi- the Nirgun ( formless timeless) paratma ne kaalika aradi ( meditated on sargun avtar-kalika) and in Sri Sarbloh Granth Sahib ji, 'Mahakal ankal kal ki murat kali'. That the Nirgun jot, Mahakal is formless, and that is not tainted by time (kal), or enticed by maya, and is the form of Kalika in the physical form (sargun). Therefore we can see that the Mahakal is neither male or female, and is not the Sargun form of Mahesh( avatar with snake around it's neck) as it is currently portrayed as. Isher is contained within Kali. In japji sahib 'Ika mai jugat vayai tin cheley parvan.' They are born out of shakti not the other way round, and Mahakal is not Mahesh, but Nirgun parmatma.
