This is the second liberation. He’s liberated by purity. This is the third liberation. He goes beyond notions of form, ceases notions of resistance, and abides in the abode of space. This is the fourth liberation. He discards the abode of space and abides in the abode of consciousness. This is the fifth liberation. He discards the abode of consciousness and abides in the abode of nothingness. This is the sixth liberation. He discards the abode of nothingness and abides in the abode with and without conception. This is the seventh liberation. The samādhi of complete cessation is the eighth liberation.”
