I read that there are 24 antarāyikā which are stated in the Vinaya. I've done a superficial search to the english Vinaya versions and I haven't found them. Could anyone that has the reference at hand or remembers where they are stated, give me a help finding them? With metta!
There are stumbling-blocks to ordination, and stumbling-blocks to realisation of the Dhamma. Which is it that you want to know?
The ordination procedure is given in the Mahāvagga, where the candidate is questioned about his suitability: “Are you a human being? Are you a man? Are you a free man (not a slave)? Are you free from debt? Are you free from military service? Have your parents permitted your going-forth? Are you fully 20 years of age (from the time of conception)? Do you have a full set or robs and an almsbowl?
The other stumbling blocks are things like concealing an offence, having insulted a noble one, etc. I don't know where to find a complete list.
"If beings knew, as I know, the results of giving & sharing, they would not eat without having given, nor would the stain of miserliness overcome their minds. Even if it were their last bite, their last mouthful, they would not eat without having shared." Iti 26
