An important element for developing faith and strength in your practice is creating and focusing on the ‘bhāv’ - the feeling/emotion of your practice and your practice space. This mantra is powerful:
I am not the mind, intellect, thought, ego, or some form of the supreme being; I neither have ears, nor tongue and I neither have nose (nostrils) nor eyes; I am not the sky, earth, light or the wind; I am the fortunate, joyful, supreme being who is the very emblem of truth, knowledge and eternal bliss.
I am consciousness and bliss. I am Shiva, I am Shiva.
I am not the most essential air that everyone breathes. Nor a part of essential five gases related to bodily functions (which are Prana, Aparna, Vyana, Udana and Samana). I am not the seven-fold material (Rasa, Rakta, Mamsa, Medas, Asthi,Majja and Shukra) that help in body’s physical development, I am not part of five coverings that help to build up the personality (food, air, mind, knowledge or wisdom and pleasure). Nor am I the five organs of action (which are speech/mouth, hands, feet, reproductive and rectum).
I have no likes or dislikes; Not I have any greed or delusion; I have no pride or arrogant vanity; Nor am I jealous of anyone or in competition with anyone ; I do not need the four main necessities of life (which are Dharma (Law of Life), Artha (Wealth), Kama (Desires) and Moksha (Liberation);
I am not attached to any righteousness or sin; I have neither pleasure nor sorrow. I have no need for any Mantra; I have no need for pilgrimages ; I have no need for any sacred scriptures; nor do I perform any sacrifise or rituals; I am neither the meal nor the one who consumes or what is consumed;I have no fear of death, nor do I have caste distinctions; I neither have a father nor mother because I was never born; I have neither kin/relatives nor friends; I have no gurus and nor am I a disciple. I am free of thoughts and beyond imagination since I have no form; I am all pervading and exist everywhere; I am the king of all sense-organs; I am always impartial to everything and everyone,; I am free from everything and I have no attachment to anything.
