Sunlight

[Stranger]

The sunlight here in Texas is so hot it can burn and be very uncomfortable.

You actually don't need "real" sunlight for the benefits.  The visible sunlight is only one component of a metaphysical stream of energy coming from the Logos into you; the important parts of the stream cannot be blocked by any physical object.  In other words, metaphysically-speaking, it's always sunny.

Alls you need to do is sit down and "imagine" sunlight flowing through you, into the head, out through the feet, allowing and welcoming it.  Notice the effects.
