Well, i got your point,but brother loving or respecting some one is completely different from saying 'i bow before you'!!!!
One should bow only infront of the creator who created every thing in this earth, heavens or universe!!! So if we love our elders n parents then...take care of them, take them to places of worship, listen to what they say, respect their thoughts,ideas, try to give them what they want, take care of their comfort or luxuries and every thing you can_______but not bowing in front of create!!!
Don't you think we should bow and worship in front of the one who is superior to all. Who is superior??.....the one who creates or that which is created???
