Happiness, Pleasure, Joy, Bliss are addressed here by Osho and we learn the different levels of development: "e;Let us start from the lowest because that will be easier to understand, thats where man biologically is born. Pleasure is physical..."e;Ordinarily, in the dictionaries you will find bliss defined as happiness, pleasure, joy. Linguistically they all appear to have a similar meaning; existentially it is not so. And you will have to understand the subtle nuances and differences; only then you may be able to catch some hold of the phenomenon called bliss.
