It takes a lot of merit, devotion and goodness inside; of course, and enlightenment. Most of the Buddhas, when they became Buddha, they don’t know it, because of the grace of the Master as well. They do feel that they’re clean, but because it’s so subtle! But they will know if they lose it! Whenever they lost the Buddhahood or their level goes down, they know it. For you it’s easy. Just keep the Five Precepts, meditate, recite the Five (Holy) Names, remember the Gift, and go straight up, sooner or later. Nothing can stop you now. Nothing can tempt you anymore. Nothing wants even to go near! Not everyone we love will return our love. It’s life. That’s life! Affinity, you know? Sometimes the enemy can come back, they hurt you in different ways. In the form of “love,” a lot of people use it to hurt each other.
