Cycle of Yugas: characteristics of Yugas - Verse 49

Sūta said:: Those Siddhis (spiritual powers and achievements) which appeared before the Devas in the first Kalpa, of their own accord (appeared before these also i.e. seven sages and Manu). When the original Siddhis ceased to exist, others began to function. Thousands of those Mantras which existed in the Kalpas gone by manifested themselves in their intellect once again.
