Paradoxically, according to the newest research, when you're looking for a profound rest cure, rather than trying to tune out, you may be better off tuning in and anchoring your awareness in the present moment. You can approach such engagement through various routes, like fully using your senses, practicing mindfulness, getting into a flow state, and—most difficult for many, but perhaps most effective—giving up the need to be in control.
Loch Kelly, A New York Buddhist-trained psychotherapist and meditation teacher, uses a technique called "resting in the heart space" to help people relinquish the reins; in his experience it provides the deepest rest in the shortest amount of time. "Traditionally, meditation focuses on getting to a state so neutral that there isn't a problem to solve. Some monks spend 20 years in isolation working on just that." But anyone, Kelly claims, can attain a sense of flow—and many of us already do through ordinary activities like gardening, knitting, working, or driving. When you're in a car, for example, you have to focus on the road as it looks in the moment and, at the same time, stay alert to continually anticipate the next move. Eventually, your brain resolves the two directions it's working in by falling into a rhythm, which leads to an open state of awareness that Kelly calls flow. You're most likely to feel it after an unfettered drive in the country—no urgent sense of time passing or future demands impinging, but rather a merging into the current, a harmony with the environment as the present unfolds. "There's something that's unhooked from the mind, prior to thought, and at the same time intelligent," Kelly says. "You can respond quickly." Entering this flow state signals the brain that you're safe, not in danger mode.
Once you've gotten a sense of what flow is, you're ready for the heart space meditation. Kelly suggests deciding ahead of time how long you can allow yourself to rest—people usually do it from one to 20 minutes, but you may want to go longer. To prepare, take a big inhalation, filling your stomach from the bottom to the top like a water pitcher. Exhale as you normally would. Next, look up and gradually allow your peripheral vision to expand, a gesture intended to keep you engaged with your surroundings. Smile to tell yourself that you're doing something you enjoy.
