Biographer Brian Hinton comments "'Enlightenment' is actually the opposite of what it sounds: it is full of doubt, not affirmation. 'I'm meditating and still I'm suffering.' He seems to be saying everything is a state of mind, you can choose to live in heaven or hell."
In a Rolling Stone review, John Swenson writes that the album Enlightenment is a sequel to Avalon Sunset and enables Morrison to have a new start (musically and spiritually). "Morrison is so pleased with his new start that he can even poke fun at his quest on the title track. 'I'm in the here and now and I'm meditating/And still I'm suffering but that's my problem,' he sings. 'Enlightenment, don't know what it is' – and he doesn't sound disturbed at all."
