In Hinduism, Prajapati is Lord of Creatures. In the earliest writings of Hinduism, Prajapati is viewed as the ultimate creator. He is said to have made the heavens and the earth, and the creatures that live within the universe. As time went on, he became associated with various major gods, especially Brahma, Vishnu, and Shiva. Prajapati was also associated to deities that personified the major forces of the universe, especially the sun and time. In early forms, Prajapati was often depicted as a lingam figure, sitting in full lotus position, preparing to give birth to all of creation.
The word Prajapati, which means Lord of Creatures, became used in later Hinduism to refer to an entire class of deities. It is said that in the time before the universe was formed, the creator Brahma created ten distinct Prajapati to assist him in creation. These can be viewed in the later cycles as distinct manifestations of Prajapati, and are given the names Atri, Angirasa, Vasishta, Bhrigu, Narada, Marichi, Pulaha, Krathu, Pulasthya, and Prachethasa.
Each of these Prajapati had distinct characteristics, and appear as characters in the various holy texts of Hinduism. Atri, for example, was a famous bard. He is known best for helping to propagate the holy word Aum. Bhrigu, on the other hand, is known as a famous astrologer, and is given as the author of the astrological text the Bhrigu Samhita from around 3000 BCE.
Belief in several deities, one of whom is deemed supreme, is replaced by the sacrificial pantheism of Prajapati (“Lord of Creatures”), who is the All. In the Upanishads, Prajapati merges with the concept of brahman, the supreme reality and substance.
In Hinduism, Prajapati (Sanskrit prajā-pati प्रजापति "lord of creatures") is a Hindu deity presiding over procreation, and protector of life. He appears as a creator deity or supreme god viswakarma above the other Vedic deities in RV 10 and in Brahmana literature. Vedic commentators also identify him with the creator referred to in the Nasadiya Sukta.
In later times, he is identified with Vishnu, Shiva, with the personifications of Time, Fire, the Sun, etc. He is also identified with various mythical progenitors, especially (Manu Smrti 1.34) the ten lords of created beings first created by Brahmā, the Prajapatis Marichi, Atri, Angiras, Pulastya, Pulaha, Kratu, Vasishtha, Prachetas or Daksha, Bhrigu, Nārada.
The Mahabharata mentions, in the words of celestial sage Narada, 14 Prajapatis (lit:caretakers of the Praja) Hiranyagarbha is the source of the creation of the Universe or the manifested cosmos in Indian philosophy, it finds mention in one hymn of the Rigveda (RV 10.121), known as the 'Hiranyagarbha sukta' and presents an important glimpse of the emerging monism, or even monotheism, in the later Vedic period, along with the Nasadiya sukta suggesting a single creator deity predating all other gods (verse 8: yó devéṣv ádhi devá éka âsīt, Griffith: "He is the God of gods, and none beside him."), in the hymn identified as Prajapati.
The Upanishads calls it the Soul of the Universe or Brahman, and elaborates that Hiranyagarbha floated around in emptiness and the darkness of the non-existence for about a year, and then broke into two halves which formed the Swarga and the Prithvi. In classical Puranic Hinduism, Hiranyagarbha is a name of Brahma, so called because he was born from a golden egg (Manusmrti 1.9), while the Mahabharata calls it the Manifest.
