By definition, light can not be contained, nor should it!    That which shows us the way and guides us through the darkness, that which provides warmth and comfort, such things were are not meant to be contained, nor should you.  Your steady hand, your wisdom at just the right moment, your compositions and creations make this world a better place to be.   The importance of solar orientation can not be stressed enough. Ones ownposition relative to the sun iscritical.  Will my shadow fall in front of or behind me.  Will I chase or be chased by my own shadow?  Will the shade from my shadow matter to anyone else? Will the weeds in the cracks in pavement not grow?  If I stand in your shadow will I be cooler?
