Acharya Prashant explains that the term luck or grace refers to something that exists outside the usual cause-and-effect framework. The ego prefers the cause-effect paradigm because it allows for a sense of doership and ownership. However, the result of an action cannot be dimensionally superior to the actor. The ego falsely believes it can remain in its lowly dimension while obtaining something from the beyond through cleverness and manipulation. This is impossible because actions are always of the same quality as the actor, whereas what is truly desired is a state beyond the self. Since the ego cannot cause liberation or godliness through its own efforts, the occurrence of such a transformation is referred to as luck. The ego struggles to accept that the process is not just unknown, but unknowable. When the ego fails to surrender and continues its blind efforts, it eventually expires and undergoes rebirth. This rebirth is not the movement of the soul, but rather the same ego returning in a new form, like old wine in a new bottle. True liberation cannot be caused by the ego; it simply happens, which is why it is described as luck or grace.
