This is the first talk in a speaker series titled Fundamental Buddhist Principles 2015. Buddha was a human being, whose mind opened to the truth of things, to the nature of life. He understood the causes of suffering, and developed a path of teaching that enables others to realize the truth of things for themselves. He was awakened, which means greed, hatred, and delusion were uprooted from his mind. So when we meditate, we examine our mind with the goal to understand what is really happening in our encounter with experience. What happens in our seeing, hearing, smelling, or tasting? What happens when we feel with our body? What happens when we think or feel emotions? Is that encounter affected by greed, hatred, or delusion? Or are we seeing the nature of these experiences arising and passing away, with a mind free of clinging? This talk also includes basic Buddhist teachings such as the Four Noble Truths, the Three Training (virtue (sila), meditation (samadhi) and wisdom (panna)), and the Three Primary Contemplative Skills that support meditation (concentration, mindfulness, and investigation).
