Venkatachalam / Venkatadri
The second one is Venkatachalam! The root ‘vem’ means sins and ‘kataha’ means burns.
So, the word venkatah means that which burns the heaps of sin.
Just touch the venkatachala and all your sins perish like the cotton flakes in the raging fires!
That is why it is called Venkatachala. Further, it is said in Venkatachala Puranam.
Venkaaromritha beejasthu katamaishwarya muchyathe
Amrithaishwarya sanghatyat venkatadririthi smirthaha
‘vem’ means immortality; and ‘kataha’ means riches; this hill is said to impart mundane (dull) wealth as well as the other wordily redemption. Hence it is called venkatah or venkatachala.
