। ॥ १२ ॥
In plain words
The clear-minded person who has really acquired all four disciplines — that one, and only that one, reaches the fruit. Not anyone else. Not even someone short by a little.
Close to the Sanskrit
The intelligent person in whom there is the full attainment of the fourfold means — of him alone is this attainment of the fruit, not of another who is deficient by anything at all.
