To be interested in outward things is not wrong in itself—it depends on the way in which one is interested. If it is done as part of the sadhana, looking on them from the true consciousness, then they become a means for the growth of the being. It is that that matters, to get the true consciousness—and it is this that comes in you when you have the sense of the Peace and the working of the Force in it. There is no real reason for discontent or dissatisfaction with yourself—since progress is being made in spite of the resistance of the lower forces. The pressure which is translated by the heaviness in the stomach has to be got rid of—it is there that there is the chief resistance still. Peace within and a cheerful confidence and gladness without is what is wanted—then this kind of nervous pressure and disorder would cease.
