We live in a culture that is all about self-improvement with air brushed models, the latest diet craze and attempting to “lean in”. We set goals with self-imposed rules to be followed until we fail and feel worse than when we started. Some people approach meditation this way with an intensity to just get it "right". Certainly, a healthy dose of discipline can come in handy but I will leave you with some words of wisdom from a British philosopher named Bob Sharples.
Don't meditate to fix yourself, to heal yourself, to improve yourself, to redeem yourself; rather, do it as an act of love, of deep warm friendship to yourself. In this way there is no longer any need for the subtle aggression of self-improvement, for the endless guilt of not doing enough. It offers the possibility of an end to the ceaseless round of trying so hard that wraps so many people's lives in a knot. Instead, there is now meditation as an act of love - How endlessly delightful and encouraging.
From Calming The Mind by Bob Sharples
How about forgetting about discipline and meditate out of an act of love for yourself?
