Good question. You may want to ask it again in the history section. As an old goat who lived through all of that I think it is fair to say that Eastern religions in general had an influence on the hippie movement and consequently the peace movement. I think it is easy to overstate this influence though since it seems to me the reason eastern religions appealed to hippies was a shared worldview since psychedelic drugs and voices such as Timothy Leary’s had influenced hippie thinking. Books by people like Alan Watts became popular reading among hippies. I think it’s probably fair to say that the countercultural image of Eastern religions also harmonized with the hippies’ self image. As I recall, though, it does not seem that devotees of Krsna were involved in extreme political activism. They seemed to occupy a marginal place in the counterculture. I think it is also fair to point out that there were significant differences between the lifestyles of hippies and the devotees of Krsna. Free love and drug use were not practiced by advocates of Krsna Consciousness. These are just some thoughts from an old goat though. I am not a historian.
