There are several grades of Buddhists which might range from novice to expert. Most Western Buddhists are in the category of novice. A novice, for example, is confused between the second skandha, feeling, and bliss or sukha. He is convinced that bliss is like feeling. But if this person had actually experienced bliss, instead of guessing, he would understand that even in pain, bliss does not subside for the reason that it is different than feeling.
On the subject of nirvana (P., nibbana), the novice unconsciously assumes that nirvana is conditioned like other things. It never dawns on him that his psychophysical body, which is completely conditioned, is incapable of being an apt instrument by which to connect with the unconditioned, that is, nirvana. Yet, he never shuts up trying to explain nirvana by way of conditions. This novice is even clueless as to the role of meditation in penetrating through the rind of the conditioned to attain nirvana, which in the Pali canon is called the Deathless Great Nibbana.
This same novice doesn’t comprehend how nirvana can be the end of suffering (duhkha). It never dawns on him that only the conditioned suffers, and since nirvana is unconditioned (P., asankhatma) suffering is impossible!
Competent Buddhists who have actually read a great deal of the Buddhist canon don’t make too many mistakes like the novice who walks down the path of delusion, hatred, and sensuality. This is why good teachers demand of beginners to STFU zip their lips until they’ve spent at least three to four years reading and studying the discourses of the Buddha. Of course, for those at a rank below novice (dimwits?) there is always learning to do zazen—just sit and sit and sit.
