Steven Friedell asked:
On Daf 62b Rava appears to disagree with R. Ada b. Ahava--or at least he indicates that those who stay away from their wives for long periods of time do so at danger to themselves. Why then did Rava send his own son away for six years?
The Kollel replies:
Rava warned against leaving one's wife without permission, he sent his son with permission.
