Janardhana – One who is the protector from anything negative. Ard’ means to beg, to ask
gatau yAcane ca janaih ardy ate yAcyate – One who is approached by His devotees for whatever they wish to get.
Dasyu-traanaat Janardanah (MahaBharata udyoga parva 71.6)
He is Janardanah because He protects people from Dasyus (Demons). He is the one who destroys those who are wicked.
Janaan Durjanaan ardayati hinasti narakaadeen gamayati iti vaa Janardanah
One who destroys the evil people or banishes them to hell.’ He does not need any help to vanquish the demon says Adi Sankaracharya.
Lets chant the Holy Name of the protector of all ordinary beings and seek to be in His protection always. In this Kaliyuga all the demons are within us itself. May we seek protection from our demoniac thoughts and remain in His thoughts and service always.
