The Sickness Unto Death
The Sickness Unto Death (Danish: Sygdommen til Døden) is a book written by Danish philosopher Søren Kierkegaard in 1849 under the pseudonym Anti-Climacus. A work of Christian existentialism, the book is about Kierkegaard's concept of despair, which he equates with the Christian concept of sin, which he terms, "the sin of despair."

Learning to Read
Learning to read is the acquisition and practice of the skills necessary to understand the meaning behind printed words. For a fairly good reader, the skill of reading should feel simple, effortless, and automatic. However, the process of learning to read is complex and builds on cognitive, linguistic, and social skills developed from a very early age. As one of the four core language skills (reading, writing, listening and speaking), reading is vital to gaining a command of the spoken language.

Principle of Least Action
The principle of least action – or, more accurately, the principle of stationary action – is a variational principle that, when applied to the action of a mechanical system, can be used to obtain the equations of motion for that system. It was historically called "least" because its solution requires finding the path of motion in space that has the least value. The principle can be used to derive Newtonian, Lagrangian and Hamiltonian equations of motion, and even general relativity (see Einstein–Hilbert action). In relativity, a different action must be minimized or maximized. The classical mechanics and electromagnetic expressions are a consequence of quantum mechanics. The stationary action method helped in the development of quantum mechanics. In 1933, the physicist Paul Dirac demonstrated how this principle can be used in quantum calculations by discerning the quantum mechanical underpinning of the principle in the quantum interference of amplitudes. Subsequently Julian Schwinger and Richard Feynman independently applied this principle in quantum electrodynamics. The principle remains central in modern physics and mathematics, being applied in thermodynamics, fluid mechanics, the theory of relativity, quantum mechanics, particle physics, and string theory and is a focus of modern mathematical investigation in Morse theory. Maupertuis' principle and Hamilton's principle exemplify the principle of stationary action. The action principle is preceded by earlier ideas in optics. In Ancient Greece , Euclid wrote in his Catoptrica that, for the path of light reflecting from a mirror, the angle of incidence equals the angle of reflection. Hero of Alexandria later showed that this path was the shortest length and least time. Scholars often credit Pierre Louis Maupertuis for formulating the principle of least action because he wrote about it in 1744 and 1746. However, Leonhard Euler discussed the principle in 1744,[ and evidence shows that Gottfried Leibniz preceded both by 39 years.

Neo-Advaita
Neo-Advaita, also called the Satsang-movement and Nondualism, is a New Religious Movement, emphasizing the direct recognition of the non-existence of the "I" or "ego," without the need of preparatory practice. Its teachings are derived from, but not authorised by, the teachings of the 20th century sage Ramana Maharshi, as interpreted and popularized by H. W. L. Poonja and several of his western students. It is part of a larger religious current called immediatism by Arthur Versluis, which has its roots in both western and eastern spirituality. Western influences are western esoteric traditions like Transcendentalism, and "New Age millennialism, self-empowerment and self-therapy". Neo-Advaita makes little use of the "traditional language or cultural frames of Advaita Vedanta", and some have criticised it for its lack of preparatory training, and regard enlightenment-experiences induced by Neo-Advaita as superficial.

Nazirite
In the Hebrew Bible, a nazirite or nazarite is one who voluntarily took a vow described in Numbers 6:1–21. "Nazarite" comes from the Hebrew word נזיר nazir meaning "consecrated" or "separated". This vow required the person to: After following these requirements for a designated interval (which would be specified in the individual's vow), the person would immerse in a mikveh and make three offerings: a lamb as a burnt offering (olah), a ewe as a sin-offering (hatat), and a ram as a peace offering (shelamim), in addition to a basket of unleavened bread, grain offerings and drink offerings, which accompanied the peace offering. They would also shave their head in the outer courtyard of the Jerusalem Temple and then place the hair on the same fire as the peace offering. (Numbers 6:18) The nazirite is described as being "holy unto YHWH" (Numbers 6:8), yet at the same time must bring a sin offering. This has led to divergent approaches to the nazirite in the Talmud, and later authorities, with some viewing the nazirite as an ideal, and others viewing him as a sinner.

Character Strengths and Virtues
The VIA Inventory of Strengths (VIA-IS), formerly known as the "Values in Action Inventory," is a proprietary psychological assessment measure designed to identify an individual's profile of character strengths. It was created by Christopher Peterson and Martin Seligman, well-known researchers in the field of positive psychology, in order to operationalize their Character Strengths and Virtues Handbook (CSV). The CSV is the positive psychology counterpart to the Diagnostic and Statistical Manual of Mental Disorders (DSM) used in traditional psychology. Unlike the DSM, which scientifically categorizes human deficits and disorders, the CSV classifies positive human strengths. Moreover, the CSV is centered on helping people recognize and build upon their strengths. This aligned with the overall goal of the positive psychology movement, which aims to make people's lives more fulfilling, rather than simply treating mental illness. Notably, the VIA-IS is the tool by which people can identify their own positive strengths and learn how to capitalize on them.

Bodhisattva Precepts
The Bodhisattva Precepts (traditional Chinese: 菩薩戒; ; pinyin: Púsà Jiè, Japanese: bosatsukai) are a set of moral codes used in Mahayana Buddhism to advance a practitioner along the path to becoming a Bodhisattva. Traditionally, monastics observed the basic moral code in Buddhism, the Prātimokṣa (such as that of the Dharmaguptaka), but in the Mahayana tradition, monks may observe the Bodhisattva Precepts as well.

Grihastha
Grihastha (Sanskrit: gr̥hastha) literally means "being in and occupied with home, family" or "householder". It refers to the second phase of an individual's life in a four age-based stages of the Hindu ashram system. It follows celibacy (bachelor student) life stage, and embodies a married life, with the duties of maintaining a home, raising a family, educating one's children, and leading a family-centred and a dharmic social life. This stage of Ashrama is conceptually followed by Vanaprastha (forest dweller, retired) and Sannyasa (renunciation). Combined with other three life stages, Hindu philosophy considers these stages as a facet of Dharma concept, something essential to completing the full development of a human being and fulfilling all the needs of the individual and society. Ancient and medieval era texts of Hinduism consider Grihastha stage as the most important of all stages in sociological context, as human beings in this stage not only pursue a virtuous life, they produce food and wealth that sustains people in other stages of life, as well as the offspring that continues mankind. The householder stage is also considered in Indian philosophy as one where the most intense physical, sexual, emotional, occupational, social and material attachments exist in a human being's life. In Indian traditions, Grihastha stage of life is a recommendation, but not a requirement. Any Brahmacharya may, if he or she wants, skip householder and retirement stage, go straight to Sannyasa stage of life, thereby renouncing worldly and materialistic pursuits and dedicating their lives to spiritual pursuits.

Electroreception
Electroreception or electroception is the biological ability to perceive natural electrical stimuli. It has been observed almost exclusively in aquatic or amphibious animals since water is a much better conductor of electricity than air. The known exceptions are the monotremes (echidnas and platypuses), cockroaches, and bees. Electroreception is used in electrolocation (detecting objects) and for electrocommunication.
