is an expression when a TV series has lost its way, going off into the realm of the silly and should be cancelled.
This thread, which has become remarkably repetitive, jumped the shark when it was suggested that the notion of the gandhabba in MN I 256-6 refers to sperm as a way of deflecting the significance of its usage. A gandhabba in the Buddhist and Brahmanical mythic structure refers to a low level celestial spirit. That the Buddha chose to use this word in the context of MN I 256-6 suggests that likely gandhabba had something of a wider meaning not found in any extant literature. In the very least, taking only what we have, in a sutta that deals at length with paticcasamuppada, the use of gandhabba suggests a way of talking about the causal conditions, beyond the merely physical, necessary for rebirth.
The gandhabba is sperm? Oh, gawd, it is time to move on. Considerable effort has been expended here to carefully, logically, and repeatedly explain the traditional Theravadin point of view, which has been repeatedly brushed aside for a highly idiosyncratic belief that, among other things, holds that rebirth must always entail a unchanging self agent notion, for which no amount of evidence otherwise makes a difference.
On E-Sangha I stayed far, far away from anti-rebirth threads for just this reason. Some lessons one learns the hard way.
