Inspired by the meditative practices developed by pioneers of Analytical Psychology like Carl Jung, DualFlow facilitates a mindful dialogue between your conscious ego and your unconscious. This is not about multiple personality disorder or anything of that nature. Rather, it’s a meditative act that allows you to explore the duality within yourself. During a session, you can seamlessly swipe between personas to switch perspectives without losing track of your conversation, experiencing the flow between your ego and unconscious mind.
