Sri Ramanuja Munaye Namaha,
Sri Velukkudi Krishnan Swami Guruvae Namaha,
Dear BhagavAta,
Sri Velukkudi Swami has said in Couple of upanyasams about Swami Ramanujar as:
1) Adhisheshan (Nithyasoori) avataram, plus
2) Sriman NarayanAn ordered Adhisheshan and gave HIS Pancha Ayudham
a) Shangham,
b) Chakkaram,
c) Vil,
d) Gadhai,
e) Vaal, plus
3) PaarthaSaarathy Perumal (SrKrishna) Himself decided to take Avatar as Swami Ramanujar, since Smt. Kanthi maami and Sri. Somayaji asked Perumal for a child same as HIM. So Perumal had no choice except to take avatar as Himself, since there is no one Equal as Him and no one Above as Him.

Hence, its being said in “Yathiraja Mangalam” slokam 19 as:
ஷெஷோ வா ஸைந்யநாதோ வா ஸ்ரீபதிர்வேதி சாத்விக்கைஹி,
Means, Is Swami Ramanujar Adhisheshan (nithyasoori) or Vishvaksenar (nithyasoori and senapathi of Perumal) or SriyaPathi (Perumal). Who is Swami Ramanujar? Is still the question all poorvacharyas are wondering and says “Swami Ramanujarikku Mangalam”.
Hence Poorvargal say, Eppadi patta Kalavai (all above 1), 2) 3) mixed together) is Our Swami Ramanujar and Hence Unique Acharyan “Jagadhacharyan” as in Yahiraja Mangalam slokam 19 as Swami is ALL-IN-ALL for us to Cherish, who has come to help Samasaris like us and get Moksham ‘SriVaikuntam’ in SAME birth with Swami Ramanujar “NirHedukai Krupai (Causeless Mercy).
