I don’t want to claim that meditation is the answer to every mental health problem. But it’s helped me, and I sometimes recommend trying it, particularly mindfulness. (And you can do mindfulness seated and at rest, or walking, or any number of routine activities—just not driving, please!).
I’ve heard a number of people say “But I just can’t still my thoughts! My mind is racing, and I give up feeling more defeated than ever!”
Mindfulness is not about forcing your mind to stop thinking. Rather, it’s about becoming aware of what you’re thinking… and then letting the thought go.
I’ve linked an article I found recently that explains it really well. TLDR (though it’s worth reading in full): A Tibetan Buddhist monk, chosen as the reincarnation of a revered predecessor, absolutely loathed being a monk as a teenager. He was angry, snarly, irritated, and a great vexation to his teachers. Angry thoughts constantly interrupted his meditation practice (and everyone around him).
One teacher gave him some advice: when you meditate, don’t be like a dog; be like a lion.
“When you throw a stone at a dog, what does he do?” he asked.
“The dog chases the stone,” I replied.
He said that was exactly what I was doing, acting like a dog—chasing each thought that came at me…
“When you throw a stone at a lion,” he continued, “the lion doesn’t care about the stone at all. Instead, it immediately turns to see who is throwing the stone. Now think about it: if someone is throwing stones at a lion, what happens next when the lion turns to look?”
“The person throwing the stone either runs away or gets eaten,” I said.
“Right you are,” said my teacher. “Either way, no more stones!… Instead of chasing the anger, grabbing it, and holding on, just be aware. Just be very gently aware of the anger instead of getting involved. Don’t reject it, but don’t dwell on it either. Just turn your attention to look gently at the thought. At that moment of turning inward to just observe, the thought will dissolve. At that moment, just exhale and rest.”
Sounds like the full article may be valuable to you then. From the article: "If you have a hundred thoughts pass through your mind in the space of a minute, it means you have a hundred supports for meditation."
