Enlightenment is as easy as nothing else in the world. Everything needs some effort, except enlightenment. Everything needs you to go somewhere, everything needs you to do some climbing the ladder -- except enlightenment.
Enlightenment is the easiest, because it is not an achievement. Don't make a goal of it... that's what is making it difficult for you. If you are feeling good and grounded in meditation, you are perfectly in the right direction. Just get all your ocean of thoughts settled. Let it become a lake without any ripples.
You drop the idea of enlightenment -- it is none of your business. Meditation is going well; that means the tree is growing well, the flowers will be coming in their own time, in their own season. No tree is worried, no tree is concerned about why the flowers have not come yet; they always come in their own time.
All that you have to take care of is that the tree should not die, that it should be nourished, that it should have a good soil, that it should be watered, that it should have your love, your friendship. All you can do is nourish your meditation, become more and more grounded and centered. One day suddenly, from nowhere... the explosion.
