How many types of Vaishnava Charama Shloka(s) exist?

Question

Charama means peak or climax, the Shloka which is given by Bhagwan as a climax to a great Dialogue and contains essence of Sharanagati(to he Lotus feet of Shriman Narayana) like BG 18.66.

Now there are various Charma Shlokas the most famous Shloka is from Bhagwad Gita.

सर्वधर्मान्परित्यज्य मामेकं शरणं व्रज।

अहं त्वा सर्वपापेभ्यो मोक्षयिष्यामि मा शुचः।।18.66।।

Abandon all varieties of Dharma, and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear. BG 18.66

Relinquishing all Dharma means the complete relinquishment of the sense of agency, possessiveness, fruits etc,. while practising of Karma Yoga, Jnana Yoga and Bhakti Yoga in the instructed way, and the realising of Me as the agent and object of worship namely the means and the end.

Answer 1

Here are the Charama Shlokas listed by the Sri Vaishnava Acharya Chinna Jeeyar Swami in this web page:

The Rama Charama Shloka is chapter 18 verse 33 of the Yuddha Kanda of the Ramayana. And the Sita Charama Shloka is chapter 113 verse 46 of the Yuddha Kanda of the Ramayana. I'm pretty sure the Varaha Charama Shloka is from a dialogue between Varaha and Bhumidevi in the Varaha Purana. The Panchajanya and Sudarshana Charama Shlokas are chanted when metal brands of the Shankha and Chakra are placed on the shoulders during Samashrayanam, the initiation ritual into Pancharatra, so they're probably from the Pancharatra Agamas. I'm not sure where the rest are from, but I can keep looking.
