A pure mind is a quiet mind undisturbed by internal patterns, and external influences. Most human beings have an internal dialogue of circuitous thought patterns that are constantly influencing their actions. I tend to call this the “committee”, and the committee is always in debate, in other words, there’s always a constant duality within oneself.
The pure mind has relinquished thoughts, especially, contradicting thoughts to ones higher good; thoughts that remove one from potential growth, and development, but instead preserve the narrow perceptions to which the mind is attached, this is ignorance.
To move through this world with pure mind means, one has to expand ones knowledge base to fill the darkness of ignorance with light, and integrate the light of truth with ones own thoughts and perceptions, all moving toward the higher good, the expansion of ones awareness. Hold the accumulated light, that it may permeate the darkness of ignorance so that you may see the truth beyond your own limited perceptions.
There must be a willingness, and a desire, to go beyond ones limitations. This is what we call a one pointed focus, with determination. This is what will serve in strengthening the mind.
To purify our mind, we must be willing to renounce our attachment to emotions that do not serve to our benefit. In other words, emotions that create a darkness in the mind and the heart that seem to hold us in place, stuck, unable to grow, and move beyond what holds us. Emotions are strong and powerful. We must be willing to release old perspectives. Not always easy to replace them with new ones, but at least be conscious of what makes us feel ill inside in our own thoughts; and how that illness is projected out on to others, and into their lives. Choosing awareness over deeply embedded negative patterns, this is best.
