Spiritual growth or development is a systematic process that involves various methods. A person needs to learn this methodical process and practice it like any other skill to attain perfection. For spiritual growth, a person must work towards increasing his knowledge and understanding what is written in scriptures and decreasing the frequency of wrongdoings along with the severity of any wrongful acts (if any). Any act that causes pain or harm to others is considered to a wrongful act. In religious terms, these wrong acts are known as sins. In simple words, a person should not just pick any books and practices without understanding their significance in the overall process of spiritual growth.
