In SriVaishnavism Ramayana finds a special place in hearts of Bhagwatas(Sri Vaishanvas) and it is known as Sharanagati Grantham.
What is the specific reason to call it Sharanagati Grantham.
Note: I already know the abstract reason i.e. because every Kanda of Ramayana has Sharanagati Involved, I need elaborate answer.
