Only Silence is complete.
A leader has to be a samadarshi, one who sees everyone as being equal; satyadarshi, who moves with the Truth; paradarshi, who is transparent in action; doordarshi, being broad-minded and a visionary; and priyadarshi, embodying love and compassion.
While fasting detoxifies the body, silence purifies speech and brings rest to the chattering mind, and meditation takes you deep into your own being.
We need to be aware of our own selves, our body, our breath, our mind, how the mind works. Become confident of who you are.
