Трета-юга

Хануман - к Бхиме: Во время Треты возникает принесение жертв и различия в дхармах и жертвенных обрядах, старательно исполняемых и приносящих плоды дарений и жертвоприношений. (Махабхарата, Араньяка-парва (книга третья), Глава 146) - https://vedatext.com/mahabharata/aranyaka-parva/glava-146-149

Religious views on origins of religions
Religions themselves (their scriptures, their teachers) claim that Religion is eternal. For example, according to christianity: "soul's nature is to be christian". And according to Krishna's devotees, "jivera svarupa haya Krishnera nitya dasa" - "nature of every soul is to serve Krishna". Mahabharata (Vedic scripture, recorded around 5000 years ago) claim that in Satya-yuga was only one dharma (religon): Vedic religion. However, in next yuga - treta-yuga, differences in religions appear (see Mahabharata, Book 3 - Aranyaka-parva, Chapter 146, when Hanuman teaches Bhima). Also, in "Laws of Manu" (first man on Earth, according to Vedas, though there were around 250 000 other Manus in this day of Brahma already. Each Manu lives for around 300 000 000 earthly years) it is said: "Vedo akhilo dharma mula" - "Vedas are the root of all dharmas (religions). For example, Zoroastrianism is considered a link (like a branch of a tree) between Vedic religion(s) and abrahamic religions.
