Alternatively, Adam Gottleib,
in “Peyote and Other Psychoactive Cacti” has this to say: “The Indians…
believe that if one’s heart is pure, the bitterness will not be tasted.
Many have found that by not cringing from the taste, but rather letting
one’s sesnses plunge directly into the center of the bitterness, a
sort of separation from the offensive flavor is experienced. One is
aware of the bitterness, but it no longer disturbs him…It is not a
difficult trick, but it takes some mental discipline.”
