Acharya Prashant defines spirituality as a rigorous process of self-inquiry into the nature of the observer. He explains that while we take the world to be real because we experience it, spirituality asks who the entity is that sits within as the experiencer, feeler, and questioner. He clarifies that spirituality is entirely distinct from religious dogma and popular culture; the two are not even distantly related. Wisdom serves to distinguish the authentic spiritual inquiry from fake or dogmatic beliefs. He references the Nirvan Shatakam by Acharya Shankara to illustrate that spirituality is a process of negation, where one realizes they are not the body, thoughts, opinions, or senses. Acharya Prashant further explains that terms like 'Shiva' in a spiritual context refer to a joyful emptiness or the absence of all nonsense, rather than the material figures or characters found in Puranic stories. He emphasizes that self-inquiry is a secular and universal necessity that involves wiping out conditioning rather than indoctrination. He asserts that the core of this inquiry is the question 'Who am I?', which is essential for the survival of the world. He concludes by stating that any realization or conclusion reached during this journey must be transcended, as the truth lies in total negation and silence. The spiritual path is one of constant movement toward an unlimited possibility, where one never settles for a final concept but continues to transcend every station of the journey.
