People use the word samadhi loosely. It is rare. I mean exceptionally rare.
Those who have experienced it know the different types of samadhi
I will merely list it
Sampragnat samadhi
- Savitarka sampragnat samadhi
- Suvichar sampragnat samadhi
- Sananda sampragnat samadhi
- Asmit sampragnat samadhi
Asampragnat samadhi
Savikalpa samadhi
Nirvikalpa samadhi
These are states above dharana and dhayana
Even after you reach samadhi the matter is not over till the highest samadhi is reached
One must tirelessly work hard. At some point, something suddenly jives and it becomes simple
Then you realize, why did I make it so difficult! And you laugh!
