”Only something as vast and deep as your True Self can make you truly and lastingly happy.”
Nisargadatta Maharaj

The only thing that blocks your happiness is the ego-program with all its limiting and negative programming that is never in harmony with your True Self and the cosmos. Depending on your upbringing and your belief system structure, it can be a quite challenging process to free yourself from past conditioning, but it is not impossible. It requires a willingness and commitment to show up for yourself on a daily basis and the desire to want to live as your True Self and embody its design. The potential for the not-self/ego program to be active is always there, but when you fully understand the nature of this parasite in your psyche, it becomes easier to disidentify from it and remove it layer by layer with the help of the invisible world. How long this process takes really depends on your genetic makeup.
