Prabhupada Japa Chanting (Mahamantra Hare Krishna).

The Brahma Vaivarta Purana (related to Rathantara kalpa) mentions a ten thousand-year period, starting from the traditional dating of the Kali Yuga epoch, during which bhakti yogis will be present. Lord Krishna foretold that Kali Yuga will be full of extreme hardships for people with ideals and values.

In the Brahma-vaivarta Purana has words spoken by Lord Krishna to Mother Ganga just before the beginning of Kali yuga (the age of quarrel and strife). Kali yuga began approximately five thousand years ago, and it has a duration of 432,000 years, leaving us with 427,000 years till the end of the present age. Within this 432,000 year period, there is a period of 10,000 years that will be a golden age. That golden age is being described below by Lord Sri Krishna. Predicted in Brahma-vaivarta Purana 4.129. The fourth part of the Brahma-vaivarta is called Kṛṣṇa-janma-khanda. Chapter 129 is called Golokarohanam, because it describes how Krishna returns to His abode. This specific dialogue is between Lord Krishna and Mother Ganga. Verse 49 is a question by Ganga, verses 50–60 are Lord Sri Krishna's answer.

"For 10,000 years of Kali such devotees of Mine will be present on earth. After the departure of My devotees there will be only one varna, Outcaste."

"(Sri Krisna said:) Lord Hari will stay on this earth for the first ten-thousand years of Kali-yuga. Till then gods will be worshipped and the Puranas and scriptures will also be present."
