For those who practise the integral Yoga, the welfare of humanity can be only a consequence and a result, it cannot be the aim. And if all the efforts to improve human conditions have miserably failed in the end in spite of all the ardour and enthusiasm and self-consecration they have inspired at first, it is precisely because the transformation of the conditions of human life can only be achieved by another preliminary transformation, the transformation of the human consciousness or at least of a few exceptional individuals capable of laying the foundations for a more widespread transformation.
