Well, first and foremost I want to share with you some of my favorite verses from the Guru Granth Sahib
When I first read these verses they really hit me hard. Science tells us how vast and grand this universe is, but I never really contemplated upon this fact before. These verses just really made me contemplate on this vast, beautiful universe we have and how if we can't even begin to describe this universe, how indescribably beautiful and powerful the being behind this all must be. Then, to realize just by the simple command of this being these complex univereses come into being, it just mystifies me.
For the Granth Sahib to be able to convey this powerful message in only six verses, would be enough to make me bow to it, but the inspiration this book has given me does not stop there. This God, is so very great that even all of the various material pleasures and joys in these worlds he has created are not comparable to having a love for him, and experiencing his divine love for you-
To be able to convey this truth in only two verses is simply amazing on its own, but when I hear Guru Arjan Dev, went through immense torture and pain at the hands of religious bigots, due to his own love for this God, and his refusal to renounce this love, I can't even express the mix of sorrow, respect and inspiration this gives me.
Even all this I've mentioned is but a small fraction of the greatness I find in the Granth Sahib. So, when I bowed down before the Granth Sahib I was bowing down to these teachings that inspired me in such a profound way, I was bowing down to the men who taught this, the men who (unfortunately in some cases) died for this, and the God they believed in.
I know this might have sound corny, but I feel this is the best way of telling you why I bowed down to the Guru Granth Sahib.
