Satyuga, also known as the Age of Truth or the Golden Age, is a concept in Hinduism that represents a period of ideal righteousness and harmony. It is believed to be the first of the four Yugas, or cosmic ages, in the Hindu cycle of time.

According to Hindu mythology, Satyuga is characterized by virtue, honesty, truthfulness, and justice. During this age, people are said to possess high moral and spiritual qualities. It is believed that in Satyuga, humans have a strong connection with the divine and lead virtuous lives. There is no deceit, violence, or suffering in this age.

The duration of Satyuga is believed to span 1,728,000 years. As each Yuga passes, the moral and spiritual qualities of humanity decline, leading to subsequent ages of progressively lesser righteousness and harmony.

After Satyuga comes Treta Yuga, followed by Dvapara Yuga and Kali Yuga, which is considered the current age. Kali Yuga is believed to be an age of darkness, where morality and spirituality decline significantly. However, it is believed that after the completion of the four Yugas, the cycle begins again with the advent of Satyuga.

It's important to note that the concept of Satyuga is primarily a religious and mythological belief within Hinduism and should be understood in that context
