Soul groups are believed to be collections of souls that share a deep, spiritual connection. These groups often consist of individuals who have known each other in past lives and come together in the current life to support each other's growth and development. The idea is that members of a soul group help one another learn important life lessons and fulfill their spiritual purposes. Each soul group may have a specific mission or theme that guides their interactions. This can include shared experiences, challenges, or goals that encourage personal and collective evolution. The concept of soul groups is often discussed in relation to reincarnation, spirituality, and personal growth.
