It's interesting how easily bodies fit together in a hug, almost as though our Creator designed our forms for embracing. A good hug from a trusted friend is great medicine when one's soul needs repair. The arms of someone who cares and a long embrace can be so comforting.
Some of us crave touch more than others. My youngest son is my kindred hugging spirit. When he was an infant, he'd seek to get as close as possible to me; when I held him, he'd press his check next to mine and hold it there. I could tell he was soaking up the comfort of his mother's nearness. Even now, at age 17, he craves long hugs from mom. I am happy to oblige. ;)
My hugging posse isn't always around for a fix when huge hugging needs are present, so I'm learning to "hug" myself and to receive "hugs" from God. Sitting still in His holy presence feels like a hug, as does prayer, and doing things that are good for me. Old fashioned good deeds feel like hugs, too. (It's funny that we feel like we've been hugged when we do for others. That's God's economy in action!)
But hugging with real arms feels good, too, which is why it's my favorite kind. :)
