The ONLY thing that ought to, can and should, fill our soul is God.
Confusion, the cause for many of us to be unable to think with clarity, often arises because we can be rather clueless about things. We can be way thrown off and muddled not because we cannot think but rather we tend to associate the thinking process with one thing or action that does not match to what we have learned. We have good reasons to find justifications for what we do, and over time we build up quite a complex set of theories about ourselves.
The irony about a learned mind lies with our simple human nature. Humans are mostly driven to be consistent in all areas of life. It is shown in our words, deeds, attitudes, opinions, beliefs, values, habits and promises. When we make a decision or take a stand, or performs an action, we strive to make all future behaviour to match our past behaviour. We can deny, manipulate, undervalue or overvalue our attributes, behaviours, motivations and talents.
