Pralayas

 According to the Vishnu Purana, 1.7.38, there are 4 types of Pralayas:

1. Nitya Pralaya: The constant dissolution of all beings, like death that occurs daily. Everyone will witness it someday. 2. Namittika Pralaya/Maha Pralaya: It is also known as Brahma Pralaya and It occurs at the end of a Kalpa when Bhagawan Brahma goes into his sleep, which is equivalent to 4.32 billion human years. A great fire consumes all three lokas- the Bhu, Bhuvah, and Shah Loka. (Will write about lokas in details) 3. Prakrutika Pralaya: It occurs at the end of one Brahma ji lifetime equivalent to 10 [to the power] 36 human years. when the whole world (Brahmanda) reunites with prakriti. (Brahma is a designation, which keep changes with one entity to other with time).

4. Atyantika Pralaya: When man attains liberation he merges with Narayana. In simple words, attaining moksha is also a kind of Pralaya.
