ETYMOLOGY - RUDRAH
Every Hindu knows that Shiva is called Rudra. But very few know the meaning of this word.
Recently I was fortunate to have its meaning quoted from Shivapurana 6-9-14 as given below:
Rur duhkham duhkha hetum va
tad dravayati yah prubhuh
rudra ityucyate tasmat
Meaning - rur is sorrow or the reason for getting sorrow. The lord who destroys that is called
rudrah who is shiva.
