"In the body there is a piece of flesh which, if it is sound, the whole body will be sound, and if it is corrupt, the whole body will be corrupt. It is the heart."
"The heart is a king and it has armies. If the king is righteous, his armies are righteous. And if the king is corrupt, his armies are corrupt."
"The heart is their king, and they are the executors of what he commands them... Nothing in their actions can be correct unless it comes from his intention and purpose, and he is responsible for them all — because every shepherd is responsible for his flock."
"There is no bliss, joy, pleasure, or even life for it except through this. This is to it like food, health, and life. If it loses food, health, and life — worries, sadness, and sorrows rush towards it from all sides."
"Whoever does righteousness, whether male or female, while he is a believer — We will surely cause him to live a good life."
"The ignorant is dead in heart and spirit, even if his body is alive; his body is a grave walking on the face of the earth."
"The more the heart is full of life, the higher its ambition and the stronger its intention and love... The good life is only attained by high ambition, sincere love, and pure will."
"I have seen sins cause the death of hearts... and the abandonment of sins is the life of hearts."
"A true man is one who fears the death of his heart, not the death of his body. Most creatures fear the death of their bodies but pay no heed to the death of their hearts."
"And My servant continues to draw near to Me with voluntary acts of worship so that I shall love him. When I love him, I am his hearing with which he hears, his sight with which he sees, his hand with which he strikes, and his foot with which he walks. If he asks of Me, I shall surely give it to him, and if he takes refuge in Me, I shall certainly grant him it."
