Appendix: these quotes, from other writings of Sri Chinmoy, were included in the first editions.

"Pray with fear. God sheds bitter tears.
  Pray with love. God smiles with the Beauty of the Golden Dawn.
  Pray with all that you have. God wings towards you to clasp you.
  Pray with all that you are. God becomes your Liberation."

"Life and death. These are the two Blessings that I have received from God.
  Life inspires me to realise the highest Truth.
  Death wants me to wake up and hurry up."

"I have realised my error. I shall no longer stay with ignorance.
  Ignorance has understood its folly. It will no longer stay with me.
  I say to ignorance: You have tortured me.
  Ignorance says to me: You have fooled me."

"Love the world. You will be suspected.
  Love God. You will be emancipated.
  Love the world with the feeling that the world is God. You will revive the truth.
  Love God with the feeling that God is the world. You will immortalise the truth."

"I look upward. I earn time.
  I look forward. I utilise time.
  I look inward. I save time.
  I look backward. I waste time."

"I stayed with death. Death offered me its life: Ignorance. Death told me that I could never see the Face of God.
  I stayed with God. He gave me His Life: Immortality. God told me that I shall not only see Him, but eventually I shall have to become God."

"YES speaks through my heart: Since there is only God, I am sure to see Him one day. Although I see Him not, I feel Him all-where.
  The mind sleeps while the heart aspires. The Heart cries for God, while the mind doubts God and shouts at Him."

"God gave me the happiest news that He loves me even if I don’t care to love Him.
  I gave God the greatest news that I think of Him although ignorance constantly thinks of me."

"When the power of love replaces the love of power, man will have a new name: God."

"When I desire, impossibility frowns at me. When I aspire, possibility beckons me. When I will, I smash the pride of impossibility and transform possibility into inevitability."

"Knowledge says that this is right and that is wrong.
  Wisdom does the right and shuns the wrong.
  Spirituality embodies the journey of knowledge and the goal of wisdom."

"To help humanity is to see Unity.
  To serve humanity is to earn Divinity.
  To possess humanity is to welcome Multiplicity."

"Never underestimate your soul’s potentiality.
  Never overestimate your body’s capacity."

"Man’s cry is the ascending soul.
  God’s Smile is the descending Goal."

"Good promises keep ever.
  Bad promises skip over."
