So anyone curious to try, I recommend first understandings how to properly meditate. After you have good experience with this can you move onto the jhanas. I highly recommend: https://www.amazon.co.uk/Right-Concentration-Practical-Guide...

If you know how to do step 1 and then follow this book to the T. You will experience the jhanas.

I however caveat, you don't want to do this. It's a bad decision. You don't want to do this, really.

>Is Jhana Really Better Than Sex?

Absolutely, up to the third jhana.

>Can Jhana Really Substitute For Other Pleasures?

The author clearly has not walked the full path. Then again someone who did would not write this blog.

>really helped people avoid addictions

Absolutely no question.

>IV. What Can Science Tell Us About Jhanas?

The science path is a bad decision.

Let folks like Robert Wright make this mistake for you. For someone like him, he almost certainly has lost the ability to enter jhana.
