Purpose of words is to create silence.
All anger is about something which has already happened. Is it of any use getting angry about something which you cannot alter?
By self-study, by observing, by being hollow and empty, you become a channel - you become a part of the Divine. You are able to feel the presence of Divinity. All the different angels and devas, all these different forms of our consciousness, start blossoming.
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.
