I will start out with the fundamental teachings of impermanence @macusantoniu, there are complicated arguments between Theravada and Mahayana, which I feel are nit-picking (giggles), the two schools agree in general regarding the details, so I will go into the Theravada view of the the Three Marks of Existence.
I suck at debating Theravada vs. Mahayana concepts of no-self and the impermanence of a thing, like our mind and body are things, things that are dependent on other things to be what they are, as a table, which is a label for bits of wood, glue, nails, varnish, etc., bits of wood are little dead cells, little cells are made out of atoms and atoms are mostly empty....hahaha
If you want to go into thoughts, feelings, memories I can give you links into how long they last, if I remember the the luminous mind, my favorite mysterious and controversial bhavanga citta, there are different types of citta, which depending on context can mean momentary.
This was my first introduction:
These three basic facts of all existence are:
- Impermanence or Change (anicca)
- Suffering or Unsatisfactoriness (dukkha)
- Not-self or Insubstantiality (anattaa).
Wow. You gave me homework enough for a year! Thanks for taking your time in answering my question and for giving it importance by providing all those valuable links. I hope that my busy schedule allows me to dig into everything you have given me.
Just read a little bit at a time @marcusantoniu and try to find examples in your daily life. I've been studying for over 20 years, and this is how I progressed, one little step at a time <3
I love to study and find examples in my life that help me understand the teachings deep down in my heart and mind.
