To understand the immeasurable, the mind must be extraordinarily quiet, still.
If you want to leave the world better than you found it, then use your heart of compassion and your life of concern.
Since, O Mazda, from the beginning, Thou didst create soul and body; mental power and knowledge and since Thou didst place life within the corporeal body and didst bestow to mankind the power to act, speak and guide, you wished that everyone should choose his or her own faith and path freely.
You love your family, but not your neighbor. You love your parents, but not others’ parents. You love your religion, but not all religions. You love your country, but not all countries. This is not true love, it is limited love. Transformation of limited love into divine love is the goal of spirituality.
