SivanandaHow will you get God's grace? When you discipline yourself. How will you know how to discipline? By observing others that had walked the path successfully to the goal of perfection. Who are these men who had walked to the goal? It is these that are known as Gurus. So you need their help, their personal example, their encouragement and their grace. Thus, we have come round to the answer that a Guru is necessary as well as his grace. Everything is necessary-\-\ Atma Kripa, Guru Kripa and Isvara Kripa.
SivanandaNever worry. Be ever cheerful. Always laugh and smile. You can use the following powerful autosuggestion: "Mr. Worry, goodbye to you. I am a different person now. I am made of sterner stuff." Worry will now be afraid to show his face to you. You can then remove the worries of many of your friends.
