"Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment" Buddha.
Meditating is a mean of changing yourself in order to develop the qualities of awareness, peace, balance, kindness, and wisdom.
When you bring conscious awareness to your activities, distractions and anxieties will gradually disappear and your mind will become more peaceful. It will also bring you a certain stability within yourself and a certain confidence with which you can face life and the complexity of the world with composure, ease and humour.
