Seeking scientific evidence on meditation's cognitive and mood benefits

Hello everyone! As someone who's always looking to optimize my health and wellness, I've been curious about meditation. While I know it's widely regarded as beneficial, I've heard mixed things about the scientific backing. I'm particularly interested in meditation's potential cognitive benefits (like improved focus and multitasking) and mood effects (helping with depression, anger, etc.). Does anyone know of any rigorous studies or strong scientific evidence supporting these specific benefits of meditation? I'd love to hear what others have found in their research or personal experiences. Thanks in advance for any insights!
