तस्यापि निरोधे सर्वनिरोधान्निर्बीजः समाधिः
tasyapi nirodhe sarva nirodhan nirbijah samadhihYoga Sutras of Patanjali, 1.51
When that too is calmed, all is calm and there is seedless samadhi.
tasyapi = that too
nirodhe = supress, restrain
sarva = all
nirodhan = supress, restrain
nirbijah = seedless
samadhih = samadhih (illumination)
I thought perhaps a metaphor for this could be when we feel love for no particular reason, it just seems to well up from somewhere within.
