basically becoming the dust of feet of all, eradicates selfishness from within,
forexample I am going to give you a simple situation, because i am a student I will give examples from what I see in my life. a lot of high scoring people, in their minds think that they are superior to others.
this robs them the opportunity to learn from others.
becoming the dust of feet of all is like, in your mind, you don't really think of yourself as anything superior. in your mind u see everyone as one.
when you do this you don't carry the burden of your ego anymore, and surprise surprise people like you more.
in my mind I was like the dust of feet of most people at school not at home (lol because still i am a human and imperfect)
people helped me so much, it was insane. i recieved help from random sources people were kind to me.
in harder situations it becomes difficult, but doing meditation keeps your mind clear so you make better decisions.
so i don't really know your situation but yes for the most part become the dust of feet of all, because carrying the burden of ego is painful
