Hello Uday,

you can try this :

trigger Handler :

public class triggerHandler {
public static boolean fact=true;

}

trigger :

trigger ContactUp on Contact (after insert,after update) {
if(triggerHandler.fact==true ){
triggerHandler.fact=false;
List<Contact> li123=[select id from contact where id in :trigger.new];
system.debug('####################');
for(contact con :li123){
con.description ='aaaaaaaaaaaaaaaa';
}
update li123;
}
}
