I would define metamorphosis as a process of change from one form to another. Everything / everyone goes through an evolution as a part of the time change. I stay transformed as a different person and continue to evolve as I grow older (and wiser 🙂 ). The most important part of my metamorphosis is to learn and remember my lessons. IMHO, the downfall of man begins when we forget our lessons or when we fail to apply our lessons of life in the correct way. Some people prefer to be ignorant to suit themselves, karma will take care of that. The lessons of life I refer to are practices and norms which every one of our forefathers have put together over generations. It is vital that we understand, respect those traditions and values.
Growing up is just not only the physiological growth of a person but the transformation process from a student to a better student. Yes, a better student because the learning process never ends even though we learn by leaps and bounds. Even after graduating with the degrees we aim for and get all the certifications needed for our jobs, the life of learning continues. As wisely stated by the great poetess Avvayar, “What you have learned is a handful; What you have not learned is a worldful.”The only reason I see it ends is either if we turn into a vegetative state or end our role in this present life. Lets make this life a meaningful one by learning and putting our knowledge to good use. Good luck!
