The above Iyah or verses denote growth in the mental aspect. When we were children we love everything and as we grow in knowledge we begin to hate and dislike many of the things that we once loved. As we grow, we began to plant in hopes to benefit from that which has been planted, and so on and so forth. This is of the law of cause and effect; action and reaction. This is a universal law and it also applies to every action that is planned and executed. We all reap what we sow, we all gather and cast. We all love and hate.
