The next line of Yoga Sutra (1.40) dwells on siddhis – at least this is what most of modern commentators think – so I shall give my brief note on this disturbing issue, all the more so as some readers have already become restless in anticipation of this theme. Let me also remind that there’s been an article on my blog dealing with yoga’ view on siddhis that was based on the report made by Dominik Wujastyk.
Now, they traditionally distinguish between supreme siddhis (or mahasiddhis) and minor siddhis – the whole of the rest.
The list of 8 supreme siddhis that can be attained by a practitioner is drawn in both early as well as late yoga texts. This is a well-known information: even Amarakosha – the major Sanskrit thesaurus – has it given on its first page, while most of texts on yoga also consider this to be conventional issue giving no list details yet introducing it as “animaadi” – anima (the first siddhi) and so on (adi).
