Then, each car will necessarily dash against the other and there is bound to be a jumble. There seems to be a very apt pattern of life that we are heading to. Every one of us is a vehicle. We know how to go forward. The point intellect is very powerful and everybody is driving but and direct it properly or guide it to the proper destination.
