When we look at fullness, plenty and abundance we naturally expand. If you notice there is an uplifting feeling of joy and security. We then tend to reflect this unto others and attract more of such experiences in our life.
Lack, scarcity or deprivation, on the other hand, constricts us and saddens us. We reflect our unhappiness on to others and attract more such experiences.
Like the saying, "when it rains it pours."
Isn't it better to have abundance pouring? Isn't gratitude- appreciation of fullness, a great attitude then?
