The easiest way to understand quality change is to consider the example of roses. These beautiful flowers, although nourished by smelly manure, do not take any of its odour (smell) or colour. They are truly like kings of gardens, in their pink, gold, red and white robes, filling the air with such a fragrance that people who come to the garden do not even notice the manure. The roots of the roses are able to transform (change) the manure to such an extent that the best is taken without any negative side effects. This is an example of quality change.
The human world is like a garden. We are like a variety of flowers surrounded by lots of manure, that is, negativity in all its forms, such as ego, fear, anger, attachment, mistrust, etc. People who are 'quality transformers' can accept all these negative things and use them for their personal growth without the negativity penetrating (entering) them; they do not get spoilt, or even touched by it. With understanding and the natural, loving detachment that comes from silence, they realise that the negative person, or situation, in front of them is the Universe’s way of giving them an opportunity to create a tiny, silent miracle in their lives. Quality transformers become the spiritual roses in the Garden of Humanity: they display all their beauty and provide inspiration for all those who see them.
