The first step to unification is getting rid of the greed inside. The next step is concentration of the mind. By this, Buddha determined that he would never stand before he got enlightened and Bodhi Dharma could sit down confronting the wall during 9 years. With this mind we should do mantra practicing or reading sutras. All the ways accomplish the same goal.
Every day recite one thousand eyes and hands sutra.
That is a good way to empty the mind. With clear minds everyone is a Buddha and a Bodhisatva. Do not make any trouble for our neighbors during our lives and lighten our clean true selves.
