Nama Dwaar Nibbles

The episode of Ajamila in Srimad Bhagavatam is well-known.  The once-pious Brahmin takes to evil deeds.  The story goes to show how, by merely chanting the Divine Name of the Lord at the last breath, the Lord comes down to rescue Ajamila.
‘Aja’ in Sanskrit means birthless. ‘Ajaa’ signifies ‘Maaya’.  ‘Milanam’ is to meet / encounter.
Ajaamila  represents one who encounters Maya and gets drowned in Maya.  ‘Ajamila’  represents the one who encounters birthlessness (liberated one).
The story shows how with the Divine Name, an ‘Ajaamila’  is transformed into ‘Ajamila’.

Lord Subrahmanya also has a name ‘Saravana Bhava’ .

What does ‘Saravana’ mean?   ‘Sara’ in Sanskrit means dried grass (‘dharba’ grass).  So ‘Sara vana’ refers to a forest of dharba grass.  Generally such a forest is very cool.

The skin of the snake is very tender and it often looks for a cool place to live. Hence snakes find home (‘bhava’) in the ‘saravana’.

It is because of the same reason that, in the Subrahmanya kshetra (in the West Coast of India), the deity is only a ‘naga’ (snake) carved in stone.

The Sanskrit term ‘nava’ means ‘new’. 
Pranava (the term used to refer the sound of ‘AUM’) can be split as ‘pra’ + ‘nava’ .
The prefix ‘pra’ can be taken as a prefix divinity to any object [for instance, sAda refers to purity, and  pra-sada is any divine offering that is done to the Lord]
Every time the Pranava is chanted, it takes one to a new plane of divinity and brings a novel transformation. 
That is perhaps a reason why it is termed ‘pra-nava’!

There are umpteen names for Lord Karthikeya or Lord Muruga.  One of them is “Subrahmanya”.

In Sanskrit, “su” denotes anything good natured.
“Brahmanya”  refers to a person who has had the experience of the Brahman (as in the Vedic verse – ‘namO brahmaNya devAya’)

Thus ‘Subrahmanya’ is a representation of a good natured person who has had the experience of Brahman.
