....beautifully put, but alas, wherefore gyan and who the dispenser ?
Let's revisit the above shabd "ਕੁੰਭੇ ਬਧਾ ਜਲੁ ਰਹੈ ਜਲ ਬਿਨੁ ਕੁੰਭੁ ਨ ਹੋਇ ॥ ਗਿਆਨ ਕਾ ਬਧਾ ਮਨੁ ਰਹੈ ਗੁਰ ਬਿਨੁ ਗਿਆਨੁ ਨ ਹੋਇ" [469, SGGSJ] - here, Guru Nanak metaphorically elobrates on the need of a Guru, meaning, teacher [master of a particular discipline, e.g. history, geography, botany, literature, music, etc].
Translation: just as water is held still in the pot [ਕੁੰਭੇ= pot made of clay] so is the mind held still by wisdom, but just as the clay pot cannot be made without water so too cannot wisdom be acquired without a qualified teacher [guru].
The operative word is Guru.
Sikhilove Ji, I fully concur with the second limb of your sentence [surrender], but before application comes understanding and before understanding comes knowledge and before knowledge comes two mediums of transportation, that is, sense data and rationality. And, how that is perceived and conceived is down to three factors, namely, genetics, environment and culture. Would you agree ?
Goodnight from down under !
