The document summarizes how moods, emotions, and feelings arise from the interaction between the body and brain. Metabolic, endocrine, autonomic, and nervous system activities influence the brain, leading to both positive states like enthusiasm and anxiety, as well as negative states like depression and helplessness. Success and failure also impact mood through these biological interactions. While some believe these processes are governed by God, nature, or randomly, the document argues that regularly practicing NAMASMARAN, or remembrance of the divine name, can reach and nurture the seeds of happiness within a person.
