Sages and spiritual Masters are not all-powerful, and they know this, which is why they deal only with those they feel are able and, above all, willing to progress. It is pointless getting indignant and saying that a spiritual Master should have enough love to deal with everyone’s evolution.
However great his love, unfortunately he can do nothing for those who feel fine as they are and refuse to improve their understanding and behaviour.
If they are satisfied with their condition, no one will be able to persuade them to change.
Ask teachers, even the most patient and devoted ones, whether they can teach anything to children who remain obstinately closed to whatever they are teaching.
Only when life shakes these children up will they understand everything they have lost by not wanting to be taught. It is the same with many adults: it is life that will shake them up and even break them into pieces, until they understand that they must be willing to become part of the movement of evolution.
