Good morning Everyone
Harkiran Ji, purpose as per Gurbani is clearly stated - look here [bold]: ਆਸਾ ਮਹਲਾ ੫ ਦੁਪਦੇ ॥ ਭਈ ਪਰਾਪਤਿ ਮਾਨੁਖ ਦੇਹੁਰੀਆ ॥ ਗੋਬਿੰਦ ਮਿਲਣ ਕੀ ਇਹ ਤੇਰੀ ਬਰੀਆ ॥ ਅਵਰਿ ਕਾਜ ਤੇਰੈ ਕਿਤੈ ਨ ਕਾਮ ॥ ਮਿਲੁ ਸਾਧਸੰਗਤਿ ਭਜੁ ਕੇਵਲ ਨਾਮ ॥੧॥ ਸਰੰਜਾਮਿ ਲਾਗੁ ਭਵਜਲ ਤਰਨ ਕੈ ॥ ਜਨਮੁ ਬ੍ਰਿਥਾ ਜਾਤ ਰੰਗਿ ਮਾਇਆ ਕੈ ॥੧॥ ਰਹਾਉ ॥ ਜਪੁ ਤਪੁ ਸੰਜਮੁ ਧਰਮੁ ਨ ਕਮਾਇਆ ॥ ਸੇਵਾ ਸਾਧ ਨ ਜਾਨਿਆ ਹਰਿ ਰਾਇਆ ॥ ਕਹੁ ਨਾਨਕ ਹਮ ਨੀਚ ਕਰੰਮਾ ॥ ਸਰਣਿ ਪਰੇ ਕੀ ਰਾਖਹੁ ਸਰਮਾ ॥੨॥੨੯॥ SGGSJ,378 II
Translation [bold]: human birth is to meet God.
Explanation
In understanding Gurbani it must be noted that this is the "word" [shabd] of God. But before exploring Gurbani and Banikars [authors of SGGSJ] active engagement with society and pre-Sikh religions, there are important considerations to be had, that is, Banikars and purpose [mission] - how do they interact ? from where does "inspiration" come ? what is its relation to the human factor ? from where are the poetry and the eloquence ? If we say it is 'of God', in what sense is it also 'of Banikars' ? Is the divine believed to be in the abeyance of human powers, or present, maximising human powers ?
Sikh thought is to the former, in that, the Banikars had no formal education to enable such graphic accounts of the metaphysical and the transcendent worlds . Hence the reason their utterance and compositions must be wholly "given" from beyond.
The compositions are not conscious deliberations, brooding on meanings and finding its own words, but rather, mouthpieces without mental forethought to sermonise the eternal message. The message is not of its own making and is authentic, in that, it is given in this way - revealed. Thus the uneducated Banikar becomes the fount of truth. By these tokens it is manifest that the person speaks from God.
The theoretical thought of Guru Nanak in constituting general principles [nam jap, vand shak and kirat kar] underpinning Sikhism is to that end - God you will meet when you walk on this path.
