I want to practice inner purification before starting meditation. I know that my mind is filled with clutter, it feels cluttered. And I want to declutter my mind while gradually achieving inner purity. I want to be more positive. And catch myself sometimes saying negative things and thinking negatively. Because if my surroundings or certain situations I find myself in. So how do I begin inner purification? How do I start? I seriously want to find inner peace and be able to grow spiritually and become a more positive thinker and being.
