Yoga Sutra 1.22 samadhi and the fruit of samadhi
Even among the ardent, there is a distinction of mild or moderate or intense
They may be mild or moderate or intense in their ardent energy, and so there is a further distinction. For the mildly ardent it is near: for the moderately ardent it is nearer: for the intensely ardent yogin who is practising intense methods, samādhi and the fruit of samādhi is nearest of all.
Even among these ardent yogin-s there are distinctions corresponding to whether their progress is slow or moderate or ardent, and this is a distinction of the saṃskāra-s created by their previous practice of the discipline. For the highest of them, the attainment of samādhi is nearest at hand.
The purpose of the sūtra is to fortify the enthusiasm of yogin-s in their practice. It is as in the world, where the prize goes to the one who runs fastest in the race. But again, by making it clear that (all) yogin-s whether slow or not do attain their aimed-at goal, it should arouse an undepressed spirit in them; those, on the other hand, who have become over-anxious as a result of fatigue from intense efforts, might lose heart (unless told the goal is near).
Is this the only way by which samādhi is soon attainable, or is there perhaps some other means?
