We often need to find the right balance in our lives, between work and home life, as well as the amount of sleep we require. That does not necessarily mean that each needs to be equal to each other. The tree in the picture has more and heavier branches on the left, but that is where the prevailing winds come from, so it needs that little extra weight there.
Usually our main concerns are mostly on the material level, but to have a ‘healthy’ balance in life the spiritual aspect must be included.
