1. There is the case of the individual who has attained internal tranquility of awareness, but not insight into phenomena through heightened discernment

2. There is the case of the individual who has attained insight into phenomena through heightened discernment, but not internal tranquility of awareness

3. There is the case of the individual who has attained neither internal tranquility of awareness nor insight into phenomena through heightened discernment

4. There is the case of the individual who has attained both internal tranquility of awareness and insight into phenomena through heightened discernment
