Let positive, strong, helpful thoughts enter into your brains from very childhood. Lay yourselves open to these thoughts, and not to weakening and paralysing ones.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies. But the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.

Those who grumble at the little thing that has fallen to their lot to do will grumble at everything. Always grumbling, they will lead a miserable life, and everything will be a failure. But those who do their duties as they go, putting their shoulders to the wheel, will see the light, and higher duties will fall to their share.
