Whenever you meet someone, you have been conditioned to consider them friends, enemies or, strangers. Further, you often react with desire, aversion or indifference.
So long as these feelings exist and become predominant, love, altruism and kindness are relegated to another part of mind. You categorize people without thinking. You invite people into your life fully, tentatively or, you reject them out of fear. You do not accept.
As you explore the nature of your mind, you begin to realize you cultivate thoughts about people that do not serve you. What can you gain from harmful thinking? This is an invitation to tame or discipline your thoughts, to envision what it would feel like to be them. If you choose to reframe how you relate to others, you dissolve your confusion.
Human beings dream of a more peaceful existence. This requires a willingness to relate to others, to view them in relation to self. As you choose to learn from people, you grow to recognize the root of your suffering is ignorance and what you were not ready to see or accept about your relationships to others. It is never to late to open your mind.
