Hardeep ji,
Its a very common mistake to just stick to.."customary..traditional..accepted...etc types of Literal Meanings of GURBANI.

GURBANI breaks all "barriers"...traditional thoughts, limits, traditions etc and strikes out into a Brand NEW direction of UNIVERSALITY..For ALL TIME and SEASONS.

Although various words have been used in Gurbani we cannot simply accept their traditional meanings...GURBANI has its OWN INDEPENDENT interpretation.
In this way..the SECOND Meaning of Amrit-Vela has a more Gurbani Raang..coloured meaning...
We must remeber Guru nanak Ji TOTALLY REJECTED all traditions/customs etc..like Janeau..sihnaan at teeraths..praying like Robots ..parrots...RITUALISM in all its forms and manners...castes, food taboos, bad days..good days..shubh/ashubh/snagrands and pooranmashis..good luck/bad luck..etc types of superstitions/vehams/bharams...special times/not special/bad times etc etc..and the traditionally accepted menaing of "amrit vela" being RESTRICTED to just a few hours of early morning fits into these rejected terms.
A Daily ROUTINE of Nitnem/bath/reading gurbani/vichaar of mukhvaak/contmeplation/meditation/attendace in Sangat in Gurdwara/listenign to Kirtan/Katha etc are ESSENTIAL to have a DISCIPLINE of REHAT...the REHAT strengthens the BODY to ACCEPT the NAAM AMRIT which is essentially for the MANN !! its FOOD and needed to keep the Mann strong and healthy...BUT restricting all this to a special time and ritualising it all defeats the purpose Guiru Ji intended us to progress in...to be CONNECTED with the Creator ALL the TIME..and not "switch off" when the sun rises !!:veryhappymunda1:
