There is a difference between earth and humanity. That is the first thing to understand if we are candidates for the yoga of transformation. To be disgusted with the very material is surely not the best of ways. Those who felt disgusted, – and there were quite a few, – chose to escape. Disgust with earth and even humanity is to, in a way, condemn the Creator. Isn’t it much better, simpler and less judgmental to look at the way things are as a limitation due to the underlying principle of Inconscience rather than feel disgusted? It brings compassion, wisdom, and shows us the path to change.
If one is indulgently enjoying the world as most do, then it is idle to even think of transformation. The return to Earth is after having found the Truth. Savitri did not feel disgusted but felt the challenge of death and fate. She did not blame the darkness but found the way to flood it with Light
Of course if our nature is very crude then perhaps there is the utility of disgust and even temporary withdrawal from earthly life so that we can be reborn into the Spirit. But that is not the path recommended in general by Sri Aurobindo and the Mother. No harm in someone following the way of disgust if that suits someone or is a need of the moment. But generally those who felt disgust strove to escape and if we see the totality of Sri Aurobindo and the Mother’s Writings and Their life, it doesn’t seem to be the most recommended path. Instead they speak of the sunlit way of the soul that progresses with faith and trust and joy and light and love knowing that His Beauty and Light and Love dwells in everything including that which we, in our superior pride sometimes or the sense of vanity, abhor and condescend.
