I thought it might be worth exploring the different opinions on the role and benefit of meditation retreats in modern Dhamma practice.
There may of course be secondary benefits associated with meditation, but I'm looking to hone in on the specific "root issue" that meditation retreats are looking to improve or resolve.
Feel free to share your personal experiences, but avoid any criticism of others.
"Having understood name-and-form, which is a product of prolificity,
And which is the root of all malady within and without,
He is released from bondage to the root of all maladies,
That Such-like-one is truly known as 'the one who has understood'." (Snp 3.6)
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
