I came across a Japanese folk song in my wanderings. . . knowing you're learning to speak Japanese, I thought to share it with you. https://www.youtube.com/watch?v=SETNAh50DCI
I found it interesting, the first video of McKenna's I pulled up had a quote "The only experience that counts, is your own." http://www.youtube.com/watch?v=GN-vMMpja30 I would just say Alan Watts, Ram Dass and Terrence McKenna all have a lot of interesting things to say on the topic.
