Different teachings may use different words yet samadhi is one but may effect the mind differently, meaning presence or absence of sensory consciousnessGoofaholix wrote: ↑Wed Nov 09, 2022 4:01 amI'm referring to the concept "ultimate samadhi", but yes "samadhi" is also a concept that we use to label an experience.
In Sanskrit teachings ( which I prefer from the word Hindu, due to it being a wide ranging label, that may not have anything to do with spirituality, or Dhamma/dharma ) there are many layers to samadhi but generally put into two forms , form and formless samadhi
samprajnata , and asamprajnata, first one being an awareness of thoughts and sense perception which is aware but not attached to thoughts and senses activity/stimulation/samprajnata and asamprajnata are which is an absorption without awareness of thoughts and sensory field , also known respectively as savikalpa samadhi and nirvikalpa samadhi
I’m not sure how these would differ experientially from form jhana and formless jhana unless one is using concepts based on externals and language of teachings
Samadhi is samadhi, if you jump in a shower and get wet with your clothes on or off the water is the same, it’s mind and it’s concepts that make differentiation
To the question can one attain full samadhi without jhana and the answer is full samadhi is unconditioned from all mental and physical phenomena , it doesn’t need jhana as it’s never bound and neither comes into or out of being
If your in full samadhi nothing more needs to be done
For me at least and is backed up by the suttas and what Buddha taught is that by insight and reflection and whatever means possible that one should abide and adhere as best as possible to the noble eightfold path
For me at least words are only pointers not to be taken to literally
