Shri Nathji would be very concerned when he saw people straying from the spiritual path for the sake of the material things of the world. He would often say:
Nature has written upon everything its price. And the price is zero! Look at the earth; it is round, like a zero. Look at the sky, the moon, the stars, all are round in shape. They all have the shape of zero. Look at the tiniest of atoms, it is round. Look at a straight line: it is made up of innumerable small dots-tiny circles, all zeroes. And, then, look at the pupil of the eye. It is round, again like a zero. And the entire universe is seen inside this pupil. A zero appearing within a zero! This is the price Nature has placed upon everything! As the Vedas say:
Neh naa naasti kinchen
Sarvam khalvidam Brahm
All that exists before us is nothing.
There is but One Reality, and He is God.
Bachashme aashikaan ghair az Khudaa hech
Zameeno aatisho aabo havaa hech!
In the eyes of the lovers of God, all is nothing!
The earth, the sky, the waters, the air–all are nothing!
