<P> Men neither bought nor sold; there were no poor and no rich; there was no need to labour, because all that men required was obtained by the power of will; the chief virtue was the abandonment of all worldly desires . The Krita Yuga was without disease; there was no lessening with the years; there was no hatred or vanity, or evil thought whatsoever; no sorrow, no fear . All mankind could attain to supreme blessedness . </P> <P> Satya Yuga lasts for 1,728,000 years, Treta Yuga 1,296,000 years, Dvapara Yuga 864,000 years and Kali Yuga 432,000 years . According to the Puranas there are 71 such cycles in a life of Manu whose life duration is 306.72 million years . The reign of fourteen Manus (4.32 billion years) comprises one day (Kalpa) of Brahma . Knowledge, meditation, and communion with Spirit hold special importance in this era . The average life expectancy of a human being in Satya Yuga is believed to be about 100,000 years . That duration of life declines in next age, Treta Yuga to 10,000 years, followed by Dvapara Yuga 1 000 years and Kali Yuga up to 100 years . During Satya Yuga, most people engage only in good, sublime deeds and mankind lives in harmony with the earth . Ashrams become devoid of wickedness and deceit . Natyam (such as Bharatanatyam), according to Natya Shastra, did not exist in the Satya Yuga "because it was the time when all people were happy". </P> <P> The Brahma Kumaris and Prajapita Brahma Kumaris make reference to five yuga in a single cycle of 5,000 years in which the Golden Age, or Satya yuga, is the first and lasts for 1,250 years . Three of the remaining four; Thretha Yuga (Silver Age), Dwarpar Yuga (Copper Age) and Kali Yuga (Iron Age), also last for 1,250 years each . The fifth age, Sangum Yuga (Confluence Age), is given to the last 100 years of the fourth age and represents the period when the Iron Age is destroyed and the next Golden Age is created. The World Drama is the story of the rise and fall of human souls during their sojourn in this world . It is about the interplay of souls, matter and God, and of the different stages through which human souls pass in five different epochs or acts of this drama. The drama begins with the Golden Age, when every soul expresses its original qualities of purity, peace, love and truth, and human relationships are marked by complete harmony . The virtuous nature of these divine beings is mirrored by nature, which is in its pristine state and serves humans with abundance . This is the time remembered as heaven or paradise by humanity . </P> <P> Golden age is the time when the human beings are full of all the divine virtues and have all the seven qualities peace, purity, love, wisdom, happiness, power and bliss to the fullest . And henceforth they are called deities, that we remember them as were our ancestors and whose divinity is worshiped in Hindu temples . The silver age comes after golden age where as time goes by, the souls, who are the actors in this drama, undergo a gradual decline . By Act Two, the number of souls has increased significantly, and though all are still happy and prosperous, the radiance and fullness that characterized their lives is no more . </P>
