Hmm.. I'd argue you need that 'melt-your-fucking-face' experience to truly experience breakthrough. But then again, people react differently to everything
Does that make what the author is trying to convey any more right/wrong? Doesn't matter if you have experience/insight through years of trial or turmoil. If you get to an enlightened state faster, more power to you. Don't discredit the author for missing whatever steps you had in mind
