Mahakaal! Yes, Lord Shiva is the death of even death.

Mahakaal! Yes, Lord Shiva is the death of even death. Bhakta markandeya was born with a limited lifespan but because he was devotee of Mahadev, when Yama tried to seize his life, Mahadev rescued him from Yama and even killed that Yama who is hailed by the name of Kaal. Therefore Shiva is the Kaal of Kaal, Mahakaal. ‪ Kaal refers to time and also death. For Mr̥ityu or Yama, the death of God. Apart from this aspect of being death of death, He is also the supreme time. Everything gets created in time, everything moves and rests in time and everything finally gets dissolved in time. However, Mahakaal is beyond the three divisions of Time, and he is the creator of Time and he is the withdrawer of Time as well. "He makes all, he knows all, the self-caused, the knower, the time of time, destroyer of time, who assumes qualities and knows everything, the master of nature and of man, the lord of the three qualities, the cause of the bondage, the existence, and the liberation of the world” ~ Svetasvatara Upanishad . Rudra is the supreme time and supreme power. he is hailed as “Mahakaal, as the time of time, the akshaya Kaal , the eternal time which is described in the Bhagawad Gita as “aham evakshayah kalo”, which means “I am the Time eternal” ~ Jai Shri Mahakal!!
