He's saying he is a mental mystic - The song is nihilistic. And so the mystic goes on 'spirit molecule' (crushing plants - dmt) journeys -- saguaro cactus (indigenous to Arizona - takes between 50-100 years to grow an arm) - not all these cacti are hallucinogenic - but we can assume what a 'mental mystic is' - Jesus (mental mystic) - however, Christ is Life itself (not some guy with buddha spinoff sayings). I suppose 'he can't get his message through to 'you' or 'them' or anyone not in the know (free spirits) - weekend wars (i suppose) could be the 'masses' or dealing with the maders that curse Life, thus curse (christ) - but what the hell do I know?
