Buddhist cosmologyBuddhist cosmology is the description of the shape and evolution of the Universe according to Buddhist scriptures and commentaries. It consists of a temporal and a spatial cosmology. The temporal cosmology describes the timespan of the creation and dissolvement of alternate universes in different aeons. The spatial cosmology consists of a vertical cosmology, the various planes of beings, into which beings are reborn due to their merits and development; and a horizontal cosmology, the distribution of these world-systems into an infinite sheet of existential dimensions included in the cycle of samsara.
Flood mythA flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primaeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".
Treta YugaTreta Yuga, in Hinduism, is the second and second best of the four yugas (world ages) in a Yuga Cycle, preceded by Krita (Satya) Yuga and followed by Dvapara Yuga. Treta Yuga lasts for 1,296,000 years (3,600 divine years). Treta means 'a collection of three things' in Sanskrit, and is so called because during the Treta Yuga, there were three Avatars of Vishnu that were seen, the fifth, sixth and seventh incarnations as Vamana, Parashurama and Rama, respectively. The bull of Dharma symbolizes that morality stood on three legs during this period.
MahakalaMahākāla is a deity common to Hinduism and Tantric Buddhism. In Buddhism, Mahākāla is regarded as the sacred Dharmapāla ("Protector of the Dharma"), while in Hinduism, Mahākāla is a fierce manifestation of the Hindu god Shiva and the consort of the goddess Mahākālī; he most prominently appears in the Kalikula sect of Shaktism. Mahākāla also appears as a protector deity in Vajrayana, Chinese Esoteric, and Tibetan Buddhism (see Citipati), and also in the Chàn and Shingon traditions.
KālaKala (काल), kɑːˈlə) is a Sanskrit term that means 'time' or 'death'. As time personified, destroying all things, Kala is a god of death, and often used as one of the epithets of Yama.

Monier-Williams's widely used Sanskrit-English dictionary lists two distinct words with the form : 1 means "black, of a dark colour, dark-blue .
Kalpa (time)A kalpa is a long period of time (aeon) in Hindu and Buddhist cosmology, generally between the creation and recreation of a world or universe. Kalpa () in this context, means "a long period of time (aeon) related to the lifetime of the universe (creation)." It is derived from कॢप् (kḷp) + -अ (-a, nominalizing suffix) (kḷp). Hindu units of timeManvantara and Yuga Cycle In Hinduism, a kalpa is equal to 4.32 billion years, a "day of Brahma" (12-hour day proper) or one thousand mahayugas, measuring the duration of the world.
BrahmalokaBrahmaloka (Sanskrit: ब्रह्मालोक, IAST: Brahmāloka) or Satyaloka (Sanskrit: सत्यलोक) is the abode of Brahma, the creator god, a member of the Trimurti along with Vishnu and Shiva, along with his consort Saraswati. It is also referred to as Brahmapura, in the Puranas. Brahmaloka is described to be 60,000,000 miles above the Prajapati loka and is considered to be of great soteriological significance. It is a sphere where the inhabitants never again know death, dwelling perpetually in the company of yogins, and drinking the excellent nectar of yoga.
Satya Yuga[[File:Kedareshwar Cave Temple , Avinash Rohra.jpg|250px|thumb|Kedareshwar Cave Temple is located at Harishchandragad, a hill fort in Ahmednagar district. Though there were four pillars surrounding the Linga, now there is only one pillar intact. Some believe the pillars to be symbols of yuga or time, namely, Satya, Treta, Dvapara , and the Kali Yuga. The temple was designed in the Hemadpanti style and is dedicated to Harishchandreshwar.
YugaA yuga, in Hinduism, is generally used to indicate an age of time. In the Rigveda, a yuga refers to generations, a period of time (whether long or short), or a yoke (joining of two things). In the Mahabharata, the words yuga and kalpa (a day of Brahma) are used interchangeably to describe the cycle of creation and destruction. In post-Vedic texts, the words "yuga" and "age" commonly denote a (pronounced Chatur Yuga), a cycle of four world ages—for example, in the Surya Siddhanta and Bhagavad Gita (part of the Mahabharata)—unless expressly limited by the name of one of its minor ages: Krita (Satya) Yuga, Treta Yuga, Dvapara Yuga, or Kali Yuga.
