Pick whatever method you want—meditation/prayer/yogas and their preparatory physical exercises…and yes, if done right, even psychedelics—but IMHO, a real spiritual experience should infuse every tired religious/positive thinking cliches with undeniably vivid life (because we know they’re true, it’s just that sometimes the people who say them are super annoying).  It is also our responsibility to BRING SOMETHING BACK from that experience—to strive to find new ways to iterate and channel that ineffability.  But if you don’t, then it’s still TOTALLY OKAY.  

(Because a real spiritual experience assures you that in the end, it’s all good.  😉 )
