Meditation is a great way to achieve a mentally clear and emotionally calm state. I'd imagine that comes in handy on the anniversary of your father's death. However, it doesn't look like it's doing much for Kevin.
Even Toby notices it! I love how he's always cheering his girl on, even when she's feeling down. Toby can never replace her Jack, but he's similar in that he'll always see her beauty, even when she doesn't.
