A selfish basis would not serve the purpose of taking a man higher and higher along the paths of evolution.
Mahatma GandhiHe who runs to the doctor, vaidya, or hakim for every little ailment, and swallows all kinds of vegetable and mineral drugs, not only curtails his life, but by becoming the slave of his body instead of remaining its master, loses self-control, and ceases to be a man.
Mahatma Gandhi
