Be Dhammakaya

There are three things follow any obsession. Desire (chanda), Rapture (piti), and Happiness (sukkha).
One desires a delicious food, when his body enjoy it, this is rapture. And when he talks about that to his friends, this is happiness.
He becomes addicted (tanha) to it. If he doesn't live with it, he feel his life is uncomplete, this is attachment (upadana).

When you are not a monk, and you suppress your dislike feeling through wrong practice such patience, the practice of abrahamic religions, then you have a disease. The disease is wrong view, that manifest as wrong act.
Patience will not do any good, it is only the way of abrahamic religions to storing alot of power, and they will use this power to commit bad deeds later. So, the moral ethics being used to perform real crime. Like fasting one month each year, so after that become fierceful like a beast.
This is called supressing mind, this is called a disease.

A buddhist should purify himself by allowing all his thoughts to arise naturally. He does that by:
1. Watching his consciousness. Anytime he want to do things he like, he awares, "this is what human do, me as a monk doesn't do such thing. I throw this thought to any human who need it."
Anytime he feel dislike of something, he awares, "this is what human do, me as a monk doesn't do such thing. I throw this thought to any human who need it."
2. Watching his subconsciousness.
Anytime he has a plan about a happy human life, he awares, "this is what human do, me as a monk doesn't do such thing. I throw this thought to any human who need it."

Having patience is not as noble as having forbereance (khanti). If you being patient, you are already lost because you feel disagree with that inside you. Those who can bear difficulty without disagreement have attained genuine wisdom.
By having forbereance, thoughts just arise naturally, cause you know when you react to your thoughts then it is just your feelings, it is just your perception. Not Dhamma.

Being empty, to be empty, is not what Buddha taught as highest Dhamma (do you find any theravada sutta that says that?). But to leave everything, to leave all your belongings is what Buddha taught (nekhamma). When you think to be empty, you become full of yourself. But when you think to leave all your belongings, finally you willbe empty.
"There is suffering" said The buddha, "there is way that lead to cessation of suffering" said The Buddha. Here we know what Buddha taught, Buddha want us to understand suffering and to cease it. It is this understanding that the real goal.

If being empty is the goal then Buddha would not called himself, "I am Dhammakaya", which means he is the body of Dhamma.
There is no way you can become empty and you call youself a Buddha. Being empty is just the state of Jhana 7. If you die in this meditative state, you reborn as The God.
Be a body of Dhamma like the Buddha. Not being empty like zen priests.

"Leave it, leave even your non-ego consciousness" - Buddha, Alagaddupama Sutta. This is all about nekhamma lesson. not about sunnata. The teaching of sunnata in Cula Sunnata Sutta is not to make you a Buddha, Buddha taught that so you understand all levels of Arupa Jhanas.
