Since there is a Jewish Buddhist movement, here is a list of ways in which (Theravada or early) Buddhism and Judaism are, as I understand, more similar to each other than either is to Christianity:
- In both, though there are things on which most members of each religion agree, there is no firm dogma, because the spiritual goal (experiencing God or Nirvana) is thought to be beyond mundane human thought. Individuals are free to explore their own spiritual feelings and beliefs, and to develop their own understandings. Prophets, Messiahs, the Buddha, and monks are people who may have had an especially clear or rich spiritual experience, but they are not God(s) themselves. Said another way: both religions are more orthopraxic than orthodoxic (i.e., less faith-based, more focused on what people do and experience than on what they believe).
- Absolute reality, God, etc. is usually thought to be some kind of unity or single substance, not a trinity, a hypostatic union (hybrid God-man), etc.
- Both are/were largely aniconic (Buddhism was in the early days) and prohibit giving anything a higher status than God or nirvanic beings.
- Like devas in Buddhism, early Judaism seems to have acknowledged polytheism (e.g., El becoming YHWH, “You shall have no other gods before me,” etc.), but neither made polytheism central to their religion.
- Hell is not forever. In Judaism, hell is more like Catholic purgatory and lasts only a short time, so that God can teach sinners a lesson. Those souls who are too bad to be redeemed are either destroyed by God, which seems much more compassionate to me than eternal torment, or continue to exist in a remorseful state. In Buddhism, the length and depth/badness of a hellish life varies based on one’s karma, with the worst hell being called avici. Both also find rebirth/reincarnation possible.
- Both generally lack a notion of original sin, though in Buddhism, the mind that is reborn has typically had many past lives and has accumulated many both good and bad traits. Both see people as a mixture of good/selfless and bad/selfish impulses, and see a Middle Way-type balance to be necessary for successfully living in the world (e.g., a person has to be a little selfish in order to have food to eat, to do a job, etc.).
- Less focus is placed on external forces (e.g., the devil, praying to angels or saints, God(s) taking physical form, etc.), which are usually considered to be metaphorical. Unlike how Christians often interpret it literally, the oft-quoted line from Genesis 1:27, that man was made in the image of God, is usually taken in Judaism to mean that a human’s nature, essence, or capacities for things like reason and intuition are similar to God’s, not that God literally has a human-like (or any corporeal) form.
- Both Buddhism’s precepts, the Brahmaviharas, etc. as well as Judaism’s kosher rules are concerned with how to kill animals as sparingly and humanely as possible. In both, the brief five-to-ten precepts/commandments are just a categorization or introduction to a much longer set of vinaya/commandments about many aspects of life.
- Both Buddhists and Jews do merit-making activities, especially as regards dead family members: https://ohr.edu/explore_judaism/ask_the_rabbi/ask_the_rabbi/1065
“Mind precedes all mental states. Mind is their chief; they are all mind-wrought” (Dhammapada 1, Acharya Buddharakkhita translation).
“Phenomena are preceded by the heart, ruled by the heart, made of the heart” (Dhammapada 1, Thanissaro Bhikkhu translation).
Here are three different ways of interpreting that famous first line of the Dhammapada:
- (A possibly animist or creationist interpretation:) There apparently exists an outside world independent of my mind, and the arrangements or configurations of most/all things in that world apparently result from the activities of human and non-human minds. For example, my house exists because many people in the past have thought that humans should live in houses for various reasons (protection from weather, animals, thieves, etc.); thought of ways to construct and sell a house in the climate, society, etc. where I live; and then constructed it. How far out/back you want to abstract this idea to nature or the universe is up to you. The Buddha didn’t offer a view about the origins of the universe.
- (A constructivist/phenomenological interpretation popular among Western Theravadists today:) Though there probably exists an outside world independent of our minds, no one can see it directly; we can each see only our own mind. Everything we see is a mind-state, a construction of our body-mind complex – mental output based on sensory input. When you think you’re seeing yourself or a world out there, all you’re really seeing are poorly measured, heavily subjectively biased mental constructs/fabrications of how the self or world might be. The only way to maybe see absolute reality is to remove one’s subjective biases through meditation and simple/ethical living, going deeper and deeper into the mind, until one can see reality clearly.
- (A later-Buddhism, possibly Vedanta-influenced interpretation:) The external world is literally made of/by mind, and has no existence except to the degree that our minds create it. In reality, there is only a single, monistic, cosmic Mind (e.g., Buddha-nature), which manifests itself as this dualistic world because it has somehow forgotten its true nature and/or developed dualistic cravings. When people realize/remember that true nature, they can wake up from this delusional dream we’re all living in.
“The present moment is not an absolute. It’s something that you’re [unconsciously] fabricating, and the goal of the practice is to learn how to fabricate it in a new [nirvanic] direction…. The present is here to be used, and the teachings are here to teach us how to use it wisely” (Thanissaro Bhikkhu, “The Use of the Present,” 2016-11-28).
“If you’re more carefully attentive to your choices in the present moment, you begin to see that you do have choices. There is some freedom here. And, the more you explore that freedom, by being skillful, the more you discover there’s something else… another kind of freedom, that’s not conditioned. The freedom of choice is something conditioned, but there is an unconditioned freedom. It’s a dimension that can be touched, and it’s right next to that freedom of choice” (Thanissaro Bhikkhu, “The Skill of Meditation”, 2016-11-29)
“Good men are constant[ly good]” (Dhammapada, 83, Lal’s translation).
“He is indeed virtuous, wise, and righteous who neither for his own sake nor for the sake of another (does any wrong), who does not crave for sons, wealth, or kingdom, and does not desire success by unjust means” (Dhammapada 84, Acharya Buddharakkhita’s translation).
“Think not lightly of evil, saying, “It will not come to me.” Drop by drop is the water pot filled. Likewise, the fool, gathering it little by little, fills himself with evil” (Dhammapada 121, Acharya Buddharakkhita’s translation).
“By not holding to fixed views, the pure-hearted one, having clarity of vision, being freed from all sense desires, is not born again into this world” (Karaniya Metta Sutta, Amaravati translation).
“As we meditate, we’re working on a skill, and the skill is to bring the mind to a state of stillness, with as much alertness and awareness as possible, because this skill lies at the basis of all other skills. If you want to be skillful in how you act, how you speak, how you think… you need to be aware of what you’re doing, and you have to be in the present moment, to watch your intentions, because your intentions shape everything” (Thanissaro Bhikkhu, “The Skill of Meditation“, 11/29/2016).
“…since Freud, the most extravagant fancies in the realm of love are considered to be perfectly normal (a person without them is regarded as a case for treatment), in the realm of death (the other great pole of human life) any strange fancies are still classed as ‘morbid’. The Suttas reverse the situation: sensual thoughts are the thoughts of a sick man (sick with ignorance and craving), and the way to health is through thoughts of foulness and the diseases of the body, and of its death and decomposition” (Ñāṇavīra Thera, “Clearing the Path”).
