Yongu thanichivam aanaNdi;

Dhaaga para uyir aanaNdi.
Vinai = action, karma; pirai = crescent moon; seeva = jiva, soul; inidhaga = sweetly; uyir = life force that animates our every action and thought; para = Supreme Being, Self.
Ramana crushed karmas (from before and after), and he became Siva on his own with the crescent moon. And he became all the jivas (souls) and also the sweet para (Supreme Self).
In Tirumandiram, Tirumoolar (one of the greatest Savaite saints in the Siddha tradition) says in verse 2611:
"தன்னை யறிந்திடும் தத்துவ ஞானிகள்
முன்னை வினையின் முடிச்சை யவிழ்ப்பர்கள்
பின்னை வினையைப் பிடித்துப் பிசைவர்கள்
சென்னியில் வைத்த சிவனரு ளாலன்றே"
(Thannai arindhidum thattuva gnanigaL
Munnai vinaiyin mudich avizhpargaL
Pinnai vinaiyai pidithu pisaivargaL
Chenniyil vaitha Sivan aruLale)
Meaning, those gnanis who know themselves, will cut the knot of karma from previous lives, hold and crush the karmas that come later in their lives, because of the grace of Siva on their heads.
Since Bhagavan is a Self Realised being and hence is Siva himself, SV says Bhagavan is beyond all karmas. (There are three types of karmas, broadly: Sanchita, which is accumulated karma from the past, Prarabdha which is what we are working out now due to part of the Sanchita karma which is bearing fruit, and Agama, which is karma waiting for us in the future due to what we are doing now.)
Another meaning is, since He is Siva with the crescent moon, he is not tainted by karmas that mere mortals are subject to, hence he will crush the karmas of the devotees who surrender to his feet. Bhagavan himself has assured us that when he said:
“Ramana will bear, as it is his fate to do, all the burdens of those who come and take refuge at his feet, and therefore they need have no fear of any sort, whatever conditions may surround them or in whatever danger they find themselves.”
Bhagavan as Lord Siva finds mention in a conversation between, Rangan, Bhagavan’s former classmate and devotee, and mother Alagammal (in The Guiding Presence book) who says to Rangan: “… as I was looking at Bhagavan, his body disappeared gradually into a Lingam like the one at Tiruchuzhi temple. The Lingam was lustrous. First, I could not believe my eyes,, I rubbed my eyes and looked again, it was the same sight still. I became frightened that he was leaving us. But again, gradually his body appeared in place of the Lingam.” [Rangan continues:] On hearing this I looked at Bhagavan, he smiled at me … I gathered from the above vision of Bhagavan that He was God Himself, and the vision was vouchsafed to mother to impress on her that she was no longer to think of him as her son but as God Supreme.”
Not only did he become Sivam, since he is That, he is also all the souls and the Supreme Being (Para), the one belong all attributes, which again was said by Bhagavan
Q: How are we supposed to treat others?
Bhagavan” There are no others.
Because to a gnani like Bhagavan, there is nothing or no one beyond the Self. Everything is the Self and is in the Self.
