Many great spiritual traditions emphasize the importance of physical, moral, and psychological cleanliness. Through maintaining bodily, emotional, and mental health, individuals establish greater serenity and stability within various domains of life: the social, economic, professional, familial, and personal. By cultivating positive energy from spiritual practices like meditation, we can enhance and enliven our level of being for the betterment of self and other. Likewise, we strengthen and protect our psyche from psychological contagion, characterized by harmful internal states and negative external influences.
