Meditation seems to be the only way. Psychedelics can give you a glimpse, but it's not anything to write home about..and that's coming from someone with the s/n blotter. The mind is inherently empty, free from grasping, but meditation is not attempting to make your mind empty, but to deal with it exactly how it is. It is the ultimate non-aggression first to yourself, then to the world outside of you. Once that is all uncovered we can play the games of aggression of lust etc should we want, but knowing these things don't belong to ourselves. Full circle so to speak, a journey that never needed to be made, but yet we seem to need to make it. It's quite the paradox, but should you be interested in starting just remember that it's better to finish.. If not, just forget the whole thing
