Dear SikhRenaissance,
I humbly reply. Article is interesting. Who was Guru Nanak Ji's Guru? Lets inquire into this:
1. Guru Nanak Ji said himself The Shabad is The Guru.
2. The question arises then what is Shabad ? Shabad translates into word, hymn, sound, verse.
3. In this case it is would be logical to say it is the Divine Word/Sound.
4. In SGGS shabad is referred to as the unstruck melody (anahad naad). This inferes it is not a sound that can be heard with regards to "hearing". But it is known - just not by hearing.
5. So - What element in our experience is known and outside of our senses (hearing, seeing, touching, tasting, smelling, thinking) ?
6. This takes years of practise but if you look carefully and honestly - you will see that the only element outside of our sensis is the knowing of "yourself". It is a very intimate knowlege.
7. Then what is this knowing of yourself ? If you look, you never find "yourself". You only find knowing and your senses present. The senses come and go (there isn't always hearing; there isn't always hearing; there isn't always thinking), but the knowing is always present. You then realize (after a signficant period of practise) there is only knowing, which is everpresent, without limits (limitless), undestructable. You then see what you thought was "you" was only the sensation of "a body." What you really are is KNOWing.
SGGS - When I am (in ego) you are not present; When I am not (in ego) you are present.
8. Guru Nanak Ji's Guru was the Absolute; the Knowing that brings about everything. It can't be talked about directly because words refere to experience and the Absolute is before experience (the senses).
