In his homily this morning, Fr KT used a very beautiful analogy to drive home his point. He was speaking of changing one's life and attitudes for the better and more importantly offering help to sustain those changes. He used the analogy of the caterpillar that transforms into a beautiful butterfly after it period of hibernation in the cocoon. As a caterpillar, it just eats and eats lot - but only leaves. Once it transforms into a butterfly, something so different from what it was earlier - it sustains the change, mainly by changing its food habit. It no more eats leaves. It merely feasts on nectar (The picture is that of a tiger swallowtail butterfly).
Moral: Wish to sustain changes you adopt in life, change your feeding (thinking) habits!
