Human energy should be properly utilized in developing the finer senses for spiritual understanding, in which lies the solution of life. Fruits, flowers, beautiful gardens, parks and reservoirs of water with ducks and swans playing in the midst of lotus flowers, and cows giving sufficient milk and butter are essential for developing the finer tissues of the human body. As against this, the dungeons of mines, factories and workshops develop demoniac propensities in the working class. The vested interests flourish at the cost of the working class, and consequently there are severe clashes between them in so many ways.
