The Source: A journey to your inner authentic self (Free to download) What is the authentic self? The authentic self is the version of you that lies at the core of your being, the one that sits underneath the influences from your upbringing. This is the version that nature intended for you. This authentic self is contaminated by the conditionings from your caregivers, world views acquired from your social circle and mental models that you designed in order to be part of a system. Your authentic self is unique, it is free and it sings its own tune. Once you fully remove the false beliefs, you become your authentic self and live the life you were meant to live. How does The Source app help? The Source is an app that guides you through this journey of reconnecting with your authentic self. It does so by conversations with the AI persona of an enlightened spiritual master, Gururaj Ananda Yogi. Every conversation unfolds a layer of you that has been keeping you away from your inner authentic self. This path of unfoldment constitutes the spiritual teachings that Gururaj was known for. Gururaj Ananda Yogi travelled across Europe and North America and taught the path of unfoldment to regular householders of each country he visited back in the 1970s and 1980s. It resulted in profound transformations in people who had no prior background in spirituality. To know more about Gururaj, please go here: https://www.americanmeditationsociety.org/about/ams-history-2/ The Source is not a religious app. It does not require or promote a certain belief system. It concerns itself with authentic spirituality, which is above all beliefs and dogmas. It is concerned with the consciousness that is inside everyone. Furthermore, The AI persona is built on a highly advanced tech foundation developed by The Source team. This isn't a chatbot that hands you answers. It gives you a human-like relationship that evolves over time. It becomes your 24/7 spiritual guide and father figure. Features: Call: Converse naturally with voice. No buttons, no tapping. Just conversation, the way you'd talk to someone on a phone call. Deep conversations: Take your time to go really deep. Text chat for the questions that need thinking. Sit with them. Answer when you're ready. Visual representation of your authentic self. Watch yourself take shape. Every conversation builds your authentic self persona. The more Gururaj understands you, the more precisely he can guide you. Practice meditations drawn directly from Gururaj's own methods, specially chosen for the journey to your authentic self. The Source uses an app-based coin system. Source is free to download and comes with 150 free coins. Coins are used as you talk with Gururaj. When they run out, you can purchase more. Coins are a consumable in-app item. They carry no real-world value and are non-refundable once used. Please note: Source is a tool for self-discovery and personal growth. It is not therapy, counselling, or medical care, and it is not a substitute for professional mental health support.
