Story :-

Once the devaas had the saapa of Durvaasa the great saint, who was a staunch devi bhakta. Hence, they were affected by the six changes. They bowed to the great maharishi who gave them the parihaara – let them take nectar from the churning of the paalaazhi, so that they can get back the nitya yauvana and can get rid of the death. This is in the paalaazhi mathana story which is very famous. Vaasuki the great serpent which was given the job of biting the great king pareekshit was now given the job of becoming the rope for churning the ocean. Mandara parvata or mountain was made the stick or ‘mattu’ with which the churning is to be done. On one side devaas and on the other side asuraas were there churning the ocean. But what appeared first from the churning process was kaalakoota visha which was sarva samhaaraka which may destroy the whole world. Hence to protect the world, Lord Paramasiva drank the poisonous kaalakoota visha. When it reached his neck or throat, goddess picked up his throat and hence it stayed there and hence Siva is called Neela kantha. It added to the beauty of Siva. Hence, Siva became Sreekantha, Neelakantha and Kaalakantha. But in the end of the churning process, nectar or amrita was obtained and by drinking it, devaas became deathless or amaraa and nirjjara. But even in spite of taking this nectar also, devaas die at the mahaapralaya kaala. But you alone are the witness, Oh! Goddess! Who witness the taandava of Sadaa Siva.

Karaalam - most dangerous
Shwelam - poison
Kabalitavatah - having swallowed
Sambhoh - to Lord Siva
Kaalakalanaa - the end of kaala or time
Na - [is] not
Yat - this means
Tanmoolam - the reason for that
Tava - [is] your
taatanka-mahimaa - divine ear ring in your ear

[according to haindavaacaara, widows wont wear ornaments specially ear ring. If Siva had to die, then Parvati the Goddess have to become widow and ear ring has to be removed from her ears, which is not right, because, actually parvati is referred as our pure consciousness which is ever there, witnessing even during the taandava of the Sadaa Siva. The pure consciousness or Brahman which is beyond time and space, which is eternal (beyond time) and all pervading (beyond space) was – it is – it will ever be.
It is told that the taatankaas are sun and moon for the ear rings of the goddess.]

Oh! Goddess! even after taking amrita [nectar] which is capable of removing the dangerous ageing and death (jaraanara and marana), all devaas including Lords Brahma, Indra get destroyed during mahaa-pralaya.

{laya – temporary death of the gross body everyday during sleep
pralaya – permanent death of the present gross body
mahaapralaya – permanent death of all bodies gross and subtle}

For Lord Siva, who consumed poison (aala kaala visha), there is no death or end and it is
because of your Taatanka mahima (divine ear ring), Oh! Janani!

Taatanka mahimaa- The great author Laksmidharar refers about this as –

Taatankasya karnaabharanasya saamartyam; taantanka-cchaayaavaatwam kaalasya naasti
kaalotpatti-sthiti-layaanaam taatankaika-niyatatwaatiti devyaah paativratya mahimaa
sarvaatisayee iti.

The famous sloka Rudram refers like this:-

Yaa te rudra sivaa tanooh sivaa viswaaha bheshajee
sivaa rudrasya bheshajee taya no mrida jeevase

[Oh! Lord Paramasiva! The goddess who is occupying half of your body is the [divine] medicine for the whole world. She is the medicine for you who is Rudra also. You are still alive even after consuming poison, because of her grace only.]
Kaalaswaroopi Lords Sun and Moon eat away the age of everybody in the world but they become your ornaments Oh! Goddess!

[during every day, everyone wakes up and during every night, everyone sleeps unaware of his own body and even the whole world]

Sowbhagya bhaaskaram refers as -

Soorya candrau sthanau devyaastaaveva nayane smrite
Ubhau taatankayugalam ityeshaa vaidikee srutih

Arunaamodini refers as :-

Ata yeva suvaasinyaa kadaacitapi karnabhooshanam na parityaajyam iti upadesah

Hence, pativrataas should never be without any ear ring in her ears.

Lalitaa Sahasranaama refers as –

Taatanka yugaleebhoota tapanotupamandalaa

Pancadaseestavam says –

Kalpopasamharana kalpita taandavasya devasya khandaparasoh
para bhairavasya paasaankusaikshava saraasana
pushpabaanaanaa saa saakshinee vijayate tava moortirekaa
