Hard truths
The Dao of the Tao Te Ching is not the eternal Dao.
The chain of mutually interdependent origin
To make this simpler for some of you to understand, I'm going to stick with the Taoist term 'Dao' (or 'Tao') to mean the way of the ancestors or the way of the elders. Dhamma works just as well but let's stick with 'Dao'. Dao is often defined as 'the way of Nature' and it is also the chain of mutually interdependent origin.
When the Chinese philosopher Lao Tzu wrote the Tao Te Ching back around 500 BC he stated explicitly that the Dao he was referring to in the Tao Te Ching was not the eternal Dao. He was implying that the Dao he was writing about was an example of the Dao.
Understanding the Dao goes hand in hand with understanding the Taoist principle of 'wu wei' or the principle of not forcing anything. The best way of explaining this is that any action which is both natural and appropriate in any given set of circumstances or situation should be effortless and not require the expending of any energy. Wu wei applies to any action or choice you make without thinking about it. You just do it, naturally, effortlessly, instinctively. When you're hungry you should eat. When you're tired you should sleep. This is a way of learning to sense and feel your way through life by constantly paying attention and always taking the path of least resistance.
It's a remarkably similar philosophy to Theravada Buddhism - or the way I was trained in way back decades ago. The other less official term for Theravada is 'The School of the Elders'. You have the Four Noble Truths but central to Theravada is the Eightfold Path - right view, right intention, right speech, right conduct, right livelihood, right effort, right mindfulness and right focus. 'Right' here means appropriate or natural. It does not mean anything moral or ethical. Just like Taoism there is no doctrine, no morality, no ethics because none is needed. If it's natural, appropriate and instinctive for you to do or think something, then you should not need to consider either ethics or morality.
This is also the most basic and fundamental principle of magic, or - if you're a disciple of Aleister Crowley - magick. In fact connecting with the Dao and acting in unity with both your environment and your inner self is really what magic is all about.
This does not mean that you should go off and find some elderly person and try to copy them or let them tell you what to do. You are not them. They are not you. It means you have to find your own individual way of living in unity and harmony with your environment, yourself and other people appropriate to whatever situation or circumstances you find yourself in. Nobody else is going to tell you how to live your life. You have to 'go through the experiences' and figure it out for yourself. Just like your parents did. And your grandparents. And whoever lived in your family tree before them.
To everything, turn, turn, turn
There is a season, turn, turn, turn
And a time to every purpose
Under Heaven
A time to be born, a time to die
A time to plant, a time to reap
A time to kill, a time to heal
A time to laugh, a time to weep...
Appropriate vs. inappropriate
Above I give you a song quote from Pete Seeger's song 'Turn Turn Turn' performed by 1960's band The Byrds. This song is based on the first eight verses of the third chapter of the Book of Ecclesiastes in the Bible. This is the exact same principle as the Dao and the way of the ancestors. It's right there in black and white in Christianity.
Now if you think about all the problems we face in the world today, in society, with regard to the environment, and all the cruelty, inhumanity, abuse, crime, racism, sexism, homophobia, ableism, transphobia, corruption, religious intolerance and bigotry, and so on. These all come down to just one thing - being inappropriate. Doesn't matter whether it's inappropriate thinking, inappropriate speech, inappropriate attitude, inappropriate beliefs, or whatever it all comes down to being inappropriate. You do not even have to think about ethics or morality, right and wrong, good and evil, you can see it for what it is in reality.
This is the simplest, most basic principle of karma and Natural Law. It doesn't even matter how you define karma, because whatever is appropriate flows naturally with the Dao, whatever isn't appropriate doesn't. Tell me, what is there for you to think about here?
The central issue here is that we are, first and foremost, inappropriate to ourselves. We conflate our Ego with reality and as a result we get sucked into narcissism.
This is something that my mentor and guide, Babu taught me during training when I was a teenager. If you have a reason, then you have a thought and a feeling. But understand that whatever makes you happy will eventually make you unhappy. Similarly whatever makes you unhappy, will also eventually make you happy. Everything flows. Nothing is fixed. Nothing is permanent. Nothing lasts. This is another hard truth that I like you to embrace - nothing is permanent, nothing lasts, for it is all flowing, changing, transforming. You must go through the experience and learn to let go of the experience and move on when it's appropriate. You have to learn how to flow just like water.
The great Tao flows everywhere.
All things are born from it,
yet it doesn’t create them.
It pours itself into its work,
yet it makes no claim.
It nourishes infinite worlds,
yet it doesn’t hold on to them.
Since it is merged with all things
and hidden in their hearts,
it can be called humble.
Since all things vanish into it
and it alone endures,
it can be called great.
It isn’t aware of its greatness;
thus it is truly great.
