"A wise friend reminded me that there were three important words to remember:
Try using them in the quantity that the order represents.
Use 'No' sparingly. It will allow you to have a certain illusory control over your life, but in excess it breeds resistance, fear, and even anger. Overuse of 'No' promotes a heaviness and rigidity in your life.
A generous sprinkling of 'Yes' throughout your life encourages openness and adventure as it leaves the door open for new possibilities. 'Yes' also encourages us to surrender the idea of control and let the heart take over. Life is never dull when you use 'Yes' frequently.
Saying and thinking 'Wow' as much as possible will inspire a sense of wonder and gratitude, reminding you of the infinite potential of the Divine Self."
~Nischala Joy Devi - from The Secret Power of Yoga in commentary on Yoga Sutra 2.6 - "When undue trust is placed in the individual self (Asmita), it is confused with the Divine Self."
