To be able to sit still, working only on your body is not enough. You also have to settle your mind, emotions, and energy.

Heaven and hell are not physical locations. You create them within yourself.

The best thing that you can do for your Guru is what is ultimately best for yourself.

Whatever you may be going through, if you are conscious about it and do a simple spiritual sadhana, it will fix itself.

The spiritual process is like a journey - constant change. Always new terrain.
