In this series, Gnani Purush (embodiment of Self knowledge) Dada Bhagwan addresses age-old unanswered questions of spiritual seekers. Dadashri offers in-depth answers to questions such as: “What is the meaning of karma?”, “How can I master the law of karma?”, “Who am I, and who is the ‘Doer’ (ego definition)?”, and “What is prakruti (non-self complex)?” Dadashri also provides spiritual explanation on the topics of: “To attain the Self, must one control the five sense organs?”, “How does one define penance?”, and “What would be the definition of repentance? For those wondering how to become more spiritual, Dadashri explains that the knowledge of Self is the beginning of true spirituality. With such spiritual development, and from understanding the law of karma, one can learn how to interact peacefully in worldly life.
