In Hunter S. Thompson's book "Hell's Angels: A Strange and Terrible Saga," he explores the experiences of individuals who have ventured into extreme lifestyles, particularly within the Hell's Angels motorcycle gang. The quote speaks to the elusive nature of certain profound experiences, suggesting that understanding these depths can only come from personal involvement and immersion. Those who have 'gone over' share a unique insight that others cannot grasp fully.

Thompson's perspective highlights the complexity of human experiences and the limits of expression when it comes to extraordinary realms. This notion resonates beyond the context of the Hell's Angels, indicating that there are truths and lessons that can only be comprehended by those who have lived them. Such sentiments remind us of the vast divide between theoretical knowledge and the realities faced by individuals who challenge conventional boundaries.
