Answer 1

The great Nature has intended us to earn our bread in the sweat of our brow. Every one, therefore, who idles away a single minute becomes to that extent a burden upon his neighbours, and to do so is to commit a breach of the very first lesson of ahimsa. Ahimsa is nothing if not a well-balance, exquisite consideration for one's neighbour, and an idle man is wanting in that elementary consideration. (YI, 11-4-1929, p. 144-15)
