• Mahadev: God of gods, Lord Shiva. The literal meaning of the word is The greatest god, where 'Maha' means Great/Greatest and 'Dev' means God.

• Adiyogi: Adiyogi refers to the originator of yoga. Taken from Sanskrit, 'Adi' means first and 'Yogi' means practitioner of yoga. It also refers to Lord Shiva as he is not only a god but the first yogi. Hence, he is also called Adiyogi.

• Samudra Manthan: The literal translation of the words 'Samudra Manthan' means churning of the sea. 'Samudra' means 'ocean', and 'Manthan' means 'Churning'.

According to Hindu texts, it was a cosmic event that led to the birth of divine goddesses, angels, and many precious valuables, including the elixir of immortality, Amrit, which I have called somras in the novel.

• Kalava: It is a red thread that is tied to the wrist by Hindus before the beginning of a religious ceremony or 'Puja'. The thread is tied on the right hand by males and on the left hand by females.

There is also a popular belief that the sanctified red thread, with the blessing of the gods, protects a person from diseases, enemies and other dangers.

• Rastala Loka: The realm of monsters or, in other words, Asuras. These demons are considered eternal enemies or foes to the Gods in heaven.
