Soulmate

Soulmate is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Soulmate rather than just read about it. In short: A soulmate is a person with whom one feels a deep or natural affinity. This connection is often associated with love, romance, intimacy, sexuality, spirituality, or compatibility, and may also involve trust and comfort.

Key takeaways

  • Soulmate belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Soulmate to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Soulmate from memory before moving on to harder problems.

Reference excerpt

A soulmate is a person with whom one feels a deep or natural affinity. This connection is often associated with love, romance, intimacy, sexuality, spirituality, or compatibility, and may also involve trust and comfort. In social science, a model titled the "soulmate model" exists. It is defined as relationships where one perfect person is designed to complete the subject romantically.

Definition and origin In contemporary usage, the term soulmate typically refers to a romantic or platonic partner with whom one shares a particularly strong bond. It is frequently used to suggest the closest relationship a person can have, and is sometimes understood as an exclusive or lifelong connection. Believers in the concept often describe soulmates as individuals who make each other feel “complete,” reflecting the idea that two souls are destined to unite. The earliest recorded use of the term soulmate in English appears in a letter by Samuel Taylor Coleridge dated 1822.

Historical usage of the concept

Judaism In rabbinic and mystical literature, the concept of bashert (Yiddish: “destined one”) conveys the idea of a divinely ordained partner. The Talmud (Sotah 2a) states that “forty days before the formation of a child, a heavenly voice proclaims whose daughter he will marry.” Kabbalistic writings elaborate that a soul is divided before birth into male and female halves, which are reunited in marriage. The Baal Shem Tov is quoted as saying: “From every human being there rises a light that reaches straight to heaven, and when two souls destined to be together meet, the streams of light join and a brighter light goes forth from the united being.”

Mythology

Lilith and Eve In Jewish folklore and later Kabbalistic writings, Adam is sometimes described as having had a first wife, Lilith, who was created from the same dust as him. According to this tradition, Lilith left Adam after refusing to submit to him, insisting instead on equality derived from their identical origin. In contrast, Eve is portrayed as Adam’s destined companion. Some rabbinic commentaries hold that her creation from Adam’s body symbolized an indissoluble union, with one interpretation suggesting that Adam was originally a dual-faced being divided at her creation.

Cain and Abel A midrashic tradition states that in early generations, each male child was born with a twin sister destined to be his spouse. This belief extended to Cain and Abel, and later to Jacob and Esau, whose companions were identified in some commentaries with Rachel and Leah.

King Solomon's daughter A lesser-known folktale concerns King Solomon, who, fearing that one of his daughters was destined to marry a poor man, secluded her in a tower deep within a forest. In the story, a bird of prey delivers her fated partner to the tower, where the two fall in love. The tale concludes with Solomon recognizing the young man’s scholarly virtues despite his lack of wealth, thereby fulfilling the destined match.

Greek mythology In Plato’s Symposium, the comic playwright Aristophanes presents a myth to explain the origin of love. According to his account, humans were originally androgynous beings with four arms, four legs, and a single head with two faces. Fearing their power, Zeus split them in half, condemning each to spend their lives searching for its missing counterpart (the term used by Plato is τὸ ἕτερον ἥμισυ, tó héteros ímisy, lit. "the other half"). Aristophanes describes this longing for unity as the source of human desire, stating that “love calls back the halves of our original nature together; it tries to make one out of two and heal the wound of human nature.”

Hinduism The story of Shiva and Parvati (Shakti) illustrates how the masculine and feminine principles are eternal and inseparable parts of the universe. The story of Radha and Krishna also illustrates divine love that breaks through all barriers.

Theosophy Within the esoteric religious movement of Theosophy, Helena Blavatsky and later writers described the soul as originally androgynous, embodying both male and female aspects. In some interpretations, these souls later divided into separate genders, a process linked symbolically to karmic consequences or estrangement from the divine. Each half was believed to reincarnate separately, with the ultimate aim of reunion once karmic debts had been resolved.

New Age In New Age thought, the concept of soulmates has been further developed by spiritual teachers such as Mark L. Prophet and Elizabeth Clare Prophet. This school of thought defines a soulmate as a distinct soul with whom an individual has shared multiple lifetimes in different roles—including those of friend, colleague, or spouse—brought together for the purpose of mutual growth or a shared mission. The Prophets emphasize that soulmates are not necessarily a single destined partner, but rather one of many spiritual companions encountered over successive reincarnations. They describe the bond as one of “parallel and mutual evolution,” capable of manifesting in romantic or fraternal forms.

Practices

Judaism In Jewish thought, the concept of a divinely ordained partner is expressed through the term bashert (Yiddish: “destined one”). Classical sources state that all souls stand before God in pairs before entering the world, and that the “Holy One” unites these couples as intended matches.

Prayer Prayer is regarded as one means of seeking one’s bashert. In the Hebrew Bible, Eliezer prays for divine guidance in finding a wife for Isaac (Genesis 24), while later rabbinic tradition recounts that Leah prayed to alter her destined match after learning that her intended partner was Esau; she was instead joined with Jacob. In some Jewish communities, additional devotional practices developed around this belief, including praying at the tombs of revered sages, or reciting the Song of Songs and selected Psalms (31, 32, 70, 72, and 124) for forty consecutive days.

Working on character traits (Middot) Although bashert conveys the idea of a destined partner, Jewish ethical teaching emphasizes that destiny is shaped by free will. Rabbinic sources caution that a person who fails to cultivate good character (middot) may lose the merit of their destined partner to another who is more deserving.

Worked examples

Example 1 — a first encounter with Soulmate

Start with the simplest possible case. Write down what Soulmate claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Soulmate before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Soulmate ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Soulmate

In research
Soulmate appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Soulmate in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Soulmate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Love, Mating, New Age, so understanding it makes those chapters shorter.
In everyday life
Look for Soulmate outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
