"Let the beauty of what you love be what you do."
Rumi

"Love and serve humanity.
Assist everyone.
Be happy, be courteous.
Be a dynamo of irrepressible joy.
Recognise God and goodness in every face.
Thre is no saint without a past and no sinner without a future.
Praise everyone. If you cannot praise someone, let them out of your life.
Be original, be inventive.
Be courageous.
Take courage again and again.
Do not imitate, be strong, be upright.
Do not lean on the crutches of others.
Think with your own head. Be yourself.
All perfection and every divine virtue are hidden within you.
Reveal them to the world.
Wisdom, too, is already within you.
Let it shine forth.
Let the Lord's grace set you free.
Let your life be that of the rose.
In silence, it speaks the language of fragrance.
Om Namaha Shivaya."

Babaji, 1984
