"There is a secret cave of spirits in Tibet. This cave is not known to the public.
The tibetan saints are sleeping in this cave. The oldmen and monks are saying that Shiva is starting to sing his mantra calling for Gods to return to the Earth. This mantra has three levels. The last level means the coming of the new era.
Listen to this sound recorded by russian enthusiasts who were allowed to visit the place near the cave where it was possible to record the sound.
This sound has no artificial changes and is presented in raw format (only noises were reducted). "
