Ask yourself; have you achieve the single-mindededly concentration? Why some people cannot achieve chanting single-mindededly? Because they are still affected by external circumstances and their mind is full of worries. What is the reason? It is because one is not focused. If we are focused, other thoughts will not arise in your chanting. Our worries and attachments are being suppressed and we will not be disturbed by the external circumstances. This is single-mindededly concentration. If one always have such concentration on chanting, the Bodhi Mind is there. If one is not sincere in seeking rebirth into Western Pure Land, you won't be able to achieve the single-mindededly concentration chanting the Buddha-name Amitabha Buddha. "Chant" means chanting the Buddha-name Amitabha Buddha. "Concentration" means single-mindededly, without any other thoughts. "Concentrated Chanting" means chanting the Buddha-name Amitabha Buddha single-mindededly, without chanting anything else. "Always" means it has always been like this, never changed and not interrupted. "The last thought" refers to the thought when a person takes his last breath at the end of his life. The last thought is very important and it determines our destination. Which path to go,it is decided in that last thought. 🙏🙏🙏 Amituofo
