Sex, drugs & meditation
Someone said to me recently that weed gives her the same sensation as meditation would. Well, masturbation gives you the same sensation as sex would, only it's not the same.
I'd say using drugs to induce sensation that resembles meditation — is like watching a movie (all the work of your imagination is done for you).
And meditating, then, is like reading a book — your imagination has to do the work, but it's fuller on so many levels. More importantly — you much more in control here.
