The definition, or whatever, of nirvitarkaa samaapatti: YS I 43 smRtiparishuddhau svarUpashUnyevArthamAtranirbhAsA nirvitarkA.
(smRti-parishuddhau svaruupa-shUny'eva [shuunyaa + iva] -artha-maatra-nirbhaasaa nirvitarkaa) That suutra is almost identical with the definition of samaadhi in connection with the siddhi's, save smRtiparishuddhi* (III 3): tadevArthamAtranirbhAsa.n svarUpashUnyamiva samAdhiH (tad eva artha-maatra-nirbhaasaM sva-ruupa-shuunyam iva samaadhiH) The main morphological difference (-aa instead of -am) is caused by samaapatti being a feminine gender word, whereas samaadhi is a masculine word. Any ideas, what could smRtiparishuddi (purification of memory) mean? * -shuddhau is the locative singular "in, on, at - etc. case"
