Yes, the Five Hindrances, the Four Foundations of Mindfulness, four of the reflections come from the Buddha. He talks about the five daily recollections: "I am of the nature to decay, I am of the nature to be diseased, I am of the nature to die, all that is mine, dear and delightful, will change and vanish. I am the owner of my Kamma, heir to my Kamma, born of my Kamma, related to my Kamma, abide supported by my Kamma. Whatever Kamma I shall do, of that I shall be the heir. Thus by us should be frequently recollected."
That is from the scriptures, about the daily recollections that the Buddha says should be reflected on often, whether one is a women or a men, lay or ordained. So these are the reflections the Buddha encourages us to reflect about. As far as the fifth one, balancing compassion with equanimity, we added that because we have a strong practice of developing compassion in the practice and it has to be balanced with equanimity. The four unselfish emotions need to be developed together and sometimes they are not taught to be developed together, and they get unbalanced. Sometimes there is an emphasis on Lovingkindness, without the balance of Compassion, and without the balance of Sympathetic Joy and Equanimity. These four unselfish emotions can't be separated, just like the Noble Eightfold Path can't be separated, because they have balancing qualities to each other.
