The BIG difference between meditation/psychedelics/self-inquiry and Kriya Yoga, is that the first 3 have been clearly defined and explained on how they work and how they help you to awaken. While with Kriya Yoga, people like Leo Gura just ask us to blindly believe that somehow it works. Surely Leo, just tell us that "one more" blind belief won't hurt you or whatever. There are hundreds of different practices, investing 1 year for each practice to see if it works is madness because these bodies don't live for hundreds of years to try them all and see which ones are the best. You can say that you can practice multiple practices at once, but how can you know that the benefits come directly from yoga practice and not from other practices??? I do not mean to say that chakras don’t exist. However, there is no consensus on what they are, where they are located, how many there are , their colors, their meaning, or how to “balance them” (if such a thing is possible). But most importantly, Kriya Yoga practices just ask you to use your imagination and imagine that the chakras exist where charlatans pinpointed in their pictures, instead of perceiving reality as it is, without mind-filters (like imagination).  And while there's no consensus on chakras, there is a long historical consensus on the ways of achieving awakening thru meditation and self-inquiry. For example Meditation (at least the concentration type) works thru silencing your mind to the point where there's no more mind, Psychedelics help you enter radical states of consciousness, Self-Inquiry works by making you realize that the label "I" is absurd. There's NO imagining, just looking at what's there without mind-filters (like beliefs). The life of these bodies are short and can end anytime, so don't waste time blindly believing people you developed trust to (like Leo Gura). Because this is a guaranteed way to failure.
