Our thoughts are not our own. We must be kind to the guests in the house or they can cause us misery.
As soon as a thought is grasped/fixated, identification stamp is done and awareness is gone.
Be kind yes. Identity papers, please.
A thought already grasped then "solid arisen me and not me" is suffering in own mind. Clevernesses aren't helping to delete my habitual grasping.
Ego concept arises in a grasped thought. Then "you concept" follow on that started thought chain-grasping. I cannot chase you-thought away with harshness since you seems to be product of me- thought. Theatre-soap in own mind, causing misery.
Teachings once given, are easy lost in habitual mist. Practice, yes.
"No phenomena thought or other are the problem but clinging".
