“Never go to sleep with bad thoughts and torturing memories. They will not help you to wake up whole and fully serene—the two states of mind and body without which no man can acquit himself well at his day's task. A child should be ushered into the chamber of sleep with serene joy.”

“People who are contented and serene sleep well. They fall asleep easily, stay asleep, and wake refreshed. Conversely, people who are anxious, stressed, or depressed do not sleep well, and chronic insomnia is strongly associated with mood disorders. These are clear correlations, but what is cause and what is effect is not clear. Most experts agree that sleep and mood are closely related, that healthy sleep can enhance emotional well-being, while insufficient quantity or quality of sleep can adversely affect it.”

“expect bad days and tears. but it's not how you wake up, it's how you go to sleep. always remember that”

“Now an extraordinary and helpful fact is that by making Mind the object of our attention, not only does the serenity which is its nature begin to well up of its own accord but its steady unchanging character itself helps spontaneously to repel all disturbing thoughts.”

“A child should never go to bed, they only wake up a day older.”

“We are not going to change the whole world, but we can change ourselves and feel free as birds. We can be serene even in the midst of calamities and, by our serenity, make others more tranquil. Serenity is contagious. If we smile at someone, he or she will smile back. And a smile costs nothing. We should plague everyone with joy. If we are to die in a minute, why not die happily, laughing?
