Acharya Prashant defines spirituality as a rigorous process of self-inquiry, centered on the fundamental question, 'Who am I?'. He explains that while we perceive the world through our senses, the essential entity is the one who looks, experiences, and feels. Spirituality is the investigation into this internal experiencer. He clarifies that spirituality is entirely distinct from religious dogma or popular culture; while they are often conflated, wisdom lies in seeing them as separate. He references the Nirvan Shatakam by Acharya Shankara to illustrate that the spiritual path involves negating all false identifications, such as the body, thoughts, opinions, and gender. When Acharya Shankara uses the term 'Shiva', he refers to a joyful emptiness and the absence of all nonsense, rather than a material deity or a character from Puranic stories. Acharya Prashant emphasizes that self-inquiry is a secular and negative process of negation, meaning it wipes out conditioning rather than indoctrinating individuals into new beliefs. He argues that this inquiry is essential for the survival of the world and should be taught to everyone regardless of their background. Addressing the nature of realization, he states that any conclusion or realization reached during the journey must be transcended, as the ultimate truth lies in total silence and emptiness. He describes the spiritual journey as an endless movement toward an unlimited possibility, often called Atman or Brahman. This path is driven by a sense of discontentment with the limited, urging the individual to never settle and to continually transcend every station until the final, invisible peak is reached.
