yeah i'm reffering to it too,budda says rupam ko maro,vedana maro, in that the cup hotness itself is mara. if you say there is a separate lakkana to and you can get cling to.it doesn't sound right?we are talking two dukkas here.. dukka as feeling/emotions and dukka as lakkana.. lakkana is a nature, not dukka (feeling)
cliging to skandas (with dukka lakkana) cause dukka (feeling)

the whole web itself is burning,avidya or not avidya the skandas itself has a deceiving nature to it.the web is born with it.not because of avidja the burning is present,rupayak hamuwana tanama burning eka present no need to cling,clinging drags sansara
