Shri Nathji often said:
If you have thousands of rupees in silver you cannot carry them. You convert them into notes, but they are still difficult to keep. You exchange them for notes of a large denomination, and the burden becomes less. Finally, you exchange these for a diamond.
This, you can easily carry in your pocket. Though it is hidden from sight, it remains with you as a source of your wealth! In a like manner I have stored my spiritual treasure within you.
