SB 9.12.6, Translation and Purport

Having achieved perfection in the power of mystic yoga, Maru still lives in a place known as Kalāpa-grāma. At the end of Kali-yuga, he will revive the lost Sūrya dynasty by begetting a son.

At least five thousand years ago, Śrīla Śukadeva Gosvāmī ascertained the existence of Maru in Kalāpa-grāma and said that Maru, having achieved a yoga-siddha body, would continue to exist until the end of Kali-yuga, which is calculated to continue for 432,000 years. Such is the perfection of mystic power. By controlling the breath, the perfect yogī can continue his life for as long as he likes. Sometimes we hear from the Vedic literature that some personalities from the Vedic age, such as Vyāsadeva and Aśvatthāmā, are still living. Here we understand that Maru is also still living. We are sometimes surprised that a mortal body can live for such a long time. The explanation of this longevity is given here by the word yoga-siddha. If one becomes perfect in the practice of yoga, he can live as long as he likes. The demonstration of some trifling yoga-siddha does not constitute perfection. Here is a factual example of perfection: a yoga-siddha can live as long as he likes.
