I have only recently started to watch videos of Sadhuguru Jaggi Vasudev (The Founder of Isha Foundation). In this regard I find his discourses and instruction very helpful and inspirational.
This particular video is how to stop the chatter of the mind. His specific instruction is not to eat bad food. This is particularly interesting for me here at Arunachala because Sri Ramana Maharshi told that the quickest way to a peaceful mind, is to eat good “sattvic” food.
However food is not only what we eat and drink, the Bhagavad Gita explains "food" is anything that feeds the 5 senses. Violent movies, loud music, spicey food, non-vegetarian food etc etc. will all agitate the mind.
