There are five clinging aggregates. Here it states that one's self clings to the five aggregates. To quote:
"It's just as when a dog is tied by a leash to a post or stake: If it walks, it walks right around that post or stake. If it stands, it stands right next to that post or stake. If it sits, it sits right next to that post or stake. If it lies down, it lies down right next to that post or stake.
"In the same way, an uninstructed run-of-the-mill person regards form as: 'This is mine, this is my self, this is what I am.' He regards feeling… perception… fabrications… consciousness as: 'This is mine, this is my self, this is what I am.' If he walks, he walks right around these five clinging-aggregates. If he stands, he stands right next to these five clinging-aggregates. If he sits, he sits right next to these five clinging-aggregates. If he lies down, he lies down right next to these five clinging-aggregates. Thus one should reflect on one's mind with every moment: 'For a long time has this mind been defiled by passion, aversion, & delusion.' From the defilement of the mind are beings defiled. From the purification of the mind are beings purified.
It is clear that one clings to the five aggregates during his or her life time. But after death the five aggregates dissolve.
My question is : are the clinging aggregates the cause of clinging after death? (Just as one clings to his own existence after death and takes rebirth)
