Sri Sri Ravi Shankar: Not at all necessary! Why fear? Love doing a head-stand is called fear. Just make it stand the right side up. Fear is on account of love. If there is no love, there will be no fear.
Tulsidas has said, 'Bhaiy bhi na hote na preet gosai'. Fear and love are two different forms of the same thing. Where there is love, there is no fear; where there is fear, there is no love. This thing manifests in these two forms.
