The question for our time is "What works?". A few thousand years ago the question was answered by simply observing the world and how it worked. There is suffering, it is possible to understand that suffering and where it comes from and there is a path away from that suffering. No grandiose 'understanding', no hierarchical system, no leader to be followed without question, just observations about how suffering arises, let go of and prevented.

The path away from suffering has a number of components, none more important than the other, all of them intertwined. Having a
right View is to not have a point of view. Thinking clearly is to accept non-thinking, that is, not thinking out of fear and anxiety of the past and the future. Realizing the only place you can do anything about either is in the present moment with
right Thinking. Recognizing that
right Speech is really just committing to loving speech and even more importantly to deeply listening to others first. This is the only way to really communicate. While
right Action is more complex each part is simple. Protect life, practice generosity, behave responsibly and consume mindfully. One of the most important tools to stay on the path is
right Concentration or cultivation of a mind that is one pointed and yet maintains evenness. We achieve these goals through
right Diligence over time. If we nourish wholesome seeds that grow in our lives and meet unwholesome seeds with mindfulness we can find our way to happiness of a sustained kind that will last. This path is easier to find and stay on if we choose a
right Livelihood. This is simply earning a living without transgressing the ideals of love and compassion. Finally living fully in the present moment is made possible by
right Mindfulness, which is the energy that simply brings us back to this present moment we are always in, when we walk we are fully aware that we are walking, when we drink tea we are fully aware that we are drinking tea, when we are unkind we are fully aware we are being unkind and can hold ourselves and other in mindfulness and find a better way of staying on the path.

This is all that we need to know to become happy and helpful to the world. My teachers have said clearly that there is no abstract Truth. Try to walk this path, if it is true for you you will find the benefits. If our understanding is incorrect it will not work and we will need to make changes. Be awake and change course if you need to. The happiness is not sort term pleasure but a deep fulfilling joy that comes with being in alignment with how the world really works and not living in a distortion of understanding that brings short term pleasure but not deep understanding and a joyful life. Ease and the ability to let go and love is the true test of if you are on the right path.
I am not a scholar, not a monk, or authorized by anyone to say what I am saying. Just trying to honestly share what I have found useful and helpful in my life. The thinking that has brought me happiness and an easier, more joy filled life.
