Whenever commandments are given they create difficulties for people, because by the time they are given they are already out of date. Life moves so fast; it is a dynamism, it is not static. It is not a stagnant pool, it is a Ganges, it goes on flowing. It is never the same for two consecutive moments. So one thing may be right this moment, and may not be right the next. Then what to do? The only possible thing is make people so aware that they themselves can decide how to respond to a changing life.
