Do not lose joy in life as you grow old in years. Let not your 'joie de vivre be crushed under the weight of years.
With an open mind, seek and listen to all the highest ideals. Consider the most enlightened thoughts. Then choose your path, person by person, each for oneself.
Seek your happiness in the happiness of all.
Happiness comes to them who bring happiness to others.
When you are in doubt abstain.
One need not scale the heights of the heavens, nor travel along the highways of the world to find Ahura Mazda. With purity of mind and holiness of heart one can find Him in one's own heart.
