Sri Matre Namaha
Durlabhā – The One Hundred & Eighty Eighth name in Lalitha Sahasranamam.
duhkhena labdhum satya
She is difficult to attain
Even the yogi has to undergo a long process (i.e., effort) to attain her
Though this nama says that She is difficult to attain, it does not say that She is not attainable. She can be attained by internal search and exploration and not by external rituals. For attaining Her, one need to have dedicated and persistent practice of meditation.
