Mankind is notoriously too dense to read the signs that God sends from time to time. We require drums to be beaten into our ears, before we should wake from our trance and hear the warning and see that to lose oneself in all, is the only way to find oneself.
Hinduism is a living organism liable to growth and decay subject to the laws of Nature. One and indivisible at the root, it has grown into a vast tree with innumerable branches. The changes in the season affect it. It has its autumn and its summer, its winter and its spring. It is, and is not, based on scriptures. It does not derive its authority from one book. Non violence has found the highest expression and application in Hinduism.
Whenever you take a step forward, you are bound to disturb something. You disturb the air as you go forward, you disturb the dust, the ground. You trample upon things. When a whole society moves forward, this trampling is on a much bigger scale; and each thing that you disturb, each vested interest which you want to remove, stands as an obstacle.
There is no yajna (sacrifice) greater than spinning calculated to bring peace to the troubled spirit, to soothe the distracted student's mind, to spiritualize his life.
