Often times we find ourselves encountered with the term \u2018manvantara\u2019, especially in Pur\u0101\u1e47ic literature. What exactly does the term stand for? The term \u2018manvantara\u2019 is explained as the lifespan of a manu, and manus are mind-born children of Brahm\u0101. Manus are patriarchs endowed with divine power that enables them to protect the universe and to ensure its smooth progress for an extended period of time. Specifically, they are responsible for the proliferation of mankind. The Sanskrit terms used for man, like \u2018m\u0101nava\u1e25\u2019 or \u2018manu\u1e63ya\u1e25\u2019 for instance, thus derive from the term manu. More importantly, the first manu, Sv\u0101yambhuva-manu is the original author of the corpus of laws that must govern man upon earth, the manu-sm\u1e5bti. \u0915\u0943\u0924\u0947 \u0915\u0943\u0924\u0947 \u0938\u094d\u092e\u0943\u0924\u0947\u0930\u094d\u0935\u093f\u092a\u094d\u0930 \u092a\u094d\u0930\u0923\u0947\u0924\u093e \u091c\u093e\u092f\u0924\u0947 \u092e\u0928\u0941\u0903\u0964 k\u1e5bte k\u1e5bte sm\u1e5btervipra pra\u1e47et\u0101 j\u0101yate manu\u1e25| With the advents of every K\u1e5bya-yuga is born manu, the author of the Sm\u1e5bti (Manu-Sm\u1e5bti). Vi\u1e63\u1e47u-Pur\u0101\u1e47a, 3.2.45 After having given himself to the act of creation, Brahm\u0101 found that the created beings did not automatically proliferate. Desirous of producing beings that would further creation, Brahm\u0101 created the Brahmar\u1e63is, the seven great sages. To his utter dismay however, Brahm\u0101 discovered that the mind-born sages were devoid of any desire or passion, and thus remained aloof from the world around. Finding his purpose defeated, Brahm\u0101 finally created the first manu, Sv\u0101yambhuva-manu in his own image. He then created \u015aatar\u016bp\u0101 from his feminine energy so that Sv\u0101yambhuva-manu could take her for his wife. In order to establish dharma, the Supreme Being incarnated as the four children of Sv\u0101yambhuva and \u015aatar\u016bp\u0101, the daughters \u0100k\u016bti and Devah\u016bti, and the sons Yaj\u00f1a and Kapila. A total of fourteen such manus are enlisted in the Pur\u0101\u1e47as for each day in Brahm\u0101\u2019s life \u2013 Sv\u0101yambhuva, Sv\u0101roci\u1e63a, Uttama, T\u0101masa, Raivata, C\u0101k\u1e63u\u1e63a, and Vaivasvata, S\u0101var\u1e47\u012b, Dak\u1e63a-S\u0101var\u1e47\u012b, Brahma-S\u0101var\u1e47\u012b, Dharma-S\u0101var\u1e47\u012b, Rudra-S\u0101var\u1e47\u012b, Deva-S\u0101var\u1e47\u012b and Indra-S\u0101var\u1e47\u012b. These manus protect and ensure the smooth progress of the worlds until naimitta-pralaya occurs. \u0928\u093f\u0936\u093e\u0935\u0938\u093e\u0928\u0947 \u0906\u0930\u092c\u094d\u0927\u094b \u0932\u094b\u0915\u0915\u0932\u094d\u092a\u094b\u093d\u0928\u0941\u0935\u0930\u094d\u0924\u0924\u0947\u0964 \u092f\u093e\u0935\u0926\u094d\u0926\u093f\u0928\u0902 \u092d\u0917\u0935\u0924\u094b \u092e\u0928\u0942\u0928\u094d \u092d\u0941\u091e\u094d\u091c\u0902\u0936\u094d\u091a\u0924\u0941\u0930\u094d\u0926\u0936\u0965 ni\u015b\u0101vas\u0101ne \u0101rabdho lokakalpo'nuvartate| y\u0101vaddina\u1e41 bhagavato man\u016bn bhu\u00f1ja\u1e41\u015bcaturda\u015ba|| At the end of (Brahm\u0101\u2019s night) the creation (of the lower worlds) follows, and is sustained through the day when the fourteen manus stand. \u015ar\u012bmadbh\u0101gavata, 3.11.23 The lifespan of each of these manus is termed a manvantara and is described to last for a period of 71 catur-yugas or cycle of four epochs. Loosely calculated, 1 catur-yuga spans 43.2 lakh mortal years. A manvantara is approximated to 30.8 crore mortal years. A manvantara becomes a significant measurement of time also because each manvantara is marked by its own Indra, its own set of Saptar\u1e63is, its unique celestials, and avat\u0101ras. \u092e\u0928\u094d\u0935\u0928\u094d\u0924\u0930\u0947\u0937\u0941 \u092e\u0928\u0935\u0938\u094d\u0924\u0926\u094d\u0935\u0902\u0936\u094d\u092f\u093e \u090b\u0937\u092f\u0903 \u0938\u0941\u0930\u093e\u0903\u0964 \u092d\u0935\u0928\u094d\u0924\u093f \u091a\u0948\u0935 \u092f\u0941\u0917\u092a\u0924\u094d\u0938\u0941\u0930\u0947\u0936\u093e\u0936\u094d\u091a\u093e\u0928\u0941 \u092f\u0947 \u091a \u0924\u093e\u0928\u094d\u0965 manvantare\u1e63u manavastadva\u1e41\u015by\u0101 \u1e5b\u1e63aya\u1e25 sur\u0101\u1e25| bhavanti caiva yugapatsure\u015b\u0101\u015bc\u0101nu ye ca t\u0101n|| In each manvantara appear manus, progeny of those manus, sages, celestials and their following (associated with that particular manvantara). \u015ar\u012bmadbh\u0101gavata, 3.11.25 In other words, the post of the king of celestials or Indra, unto whom sacrifices are offered in the sacred fire, changes with every manvantara, as do the celestials for that manvantara. The post of the saptar\u1e63is, who descend upon earth in order to revive the Vedas lost after each catur-yuga, changes with every manvantara, and the offspring of Manu who rule over the earth also changes with every manvantara. Each manvantara is marked by its own set of avat\u0101ras was well. For instance, the Vi\u1e63\u1e47u-Pur\u0101\u1e47a states that the present age is guarded by the Manu, Vaivasvata. Indra during the Vaivasvata manvantara is Purandara. The Saptar\u1e63is are Va\u015bi\u1e63\u1e6dha, Ka\u015byapa, Atri, Jamadagni, Gautama, Vi\u015bv\u0101mitra and Bharadv\u0101ja. The illustrious sons of Vaivasvata-Manu who were emperors upon earth are Ik\u1e63v\u0101ku, N\u0101bh\u0101ga, Dh\u1e5b\u1e63\u1e6da, Sany\u0101ti, Nari\u015byanta, N\u0101bhanidi\u1e63\u1e6da, Kar\u016b\u015ba, P\u1e5b\u1e63adhara and Vasum\u0101n. Avat\u0101ras of the divine too are represented in terms of the manvantara they occurred during. For instance, the K\u016brm\u0101vat\u0101ra is said to have occurred during the C\u0101k\u1e63u\u1e63a-manvantara. Each manvantara in essence thus becomes a period of time in the endless fabric of time in the Bh\u0101rat\u012bya tradition to be associated with celestial occurrences. Pur\u0101\u1e47as therefore classify anecdotes with regards to the manvantara they took place during, and are arranged according to the chronology of manvantaras they are associated with. The \u015ar\u012bmadbh\u0101gavata states that Lord himself carries out the duties of the various manus. \u092e\u0928\u094d\u0935\u0928\u094d\u0924\u0930\u0947\u0937\u0941 \u092d\u0917\u0935\u093e\u0928\u094d \u092c\u093f\u092d\u094d\u0930\u0924\u094d\u0938\u0924\u094d\u0935\u0902 \u0938\u094d\u0935\u092e\u0942\u0930\u094d\u0924\u093f\u092d\u093f\u0903\u0964 \u092e\u0928\u094d\u0935\u093e\u0926\u093f\u092d\u093f\u0930\u093f\u0926\u0902 \u0935\u093f\u0936\u094d\u0935\u092e\u0935\u0924\u094d\u092f\u0941\u0926\u093f\u0924\u092a\u094c\u0930\u0941\u0937\u0903\u0965 manvantare\u1e63u bhagav\u0101n bibhratsatva\u1e41 svam\u016brtibhi\u1e25| manv\u0101dibhirida\u1e41 vi\u015bvamavatyuditapauru\u1e63a\u1e25||\u2028 In each manvantara, the Supreme lord, his valor apparent, resorts to the attribute of satva and manifests as the various manus in order to protect the universe. \u015ar\u012bmadbh\u0101gavata, 3.11.27 When the prescribed duty of a particular manu is completed, he was replaced by the next manu in line, and the order of the universe became the responsibility of the new manu. In this manner, the lord maintains order in the universe, and provides with the manvantara, particular periods in time, for the unraveling of cosmic events.
