Why was this Knowledge ( only for those purified in Soul and awakened in Spirit ) lost ? Due to the cataclysmic upheavals of Time. And how are the Raja Rishies, Philosopher KIngs redeeming it ? Evam Parampa Praptam / Imam Rajarshayo Vidu / Sa Kaleneva Mahata / Yogo Nashta Parantapa. The Redeemer is born in the family of Philosopher KIngs and is initiated into the Guru Parampara, in order to revive this Superconscient Knowledge, which was lost due the cyclical upheavals of Time !
