Etymology

The modern English word Heaven derives from the word heven around 1150, which developed from the Old English heofon around 1000 referring to the Christianized "place where God dwells" but earlier meaning "sky, firmament" (attested from around 725 in Beowulf); this is cognate with other Germanic languages - Old Saxon heƀan ("sky, heaven"), Middle Low German heven ("sky"), Old Icelandic himinn ("sky, heaven"), Gothic himins, and existed in variation with a related word having an -l suffix: Old Frisian himel, himul ("sky, heaven"), Old Saxon/Old High German himil, Dutch hemel, and modern German Himmel, all of which derive from the reconstructed Proto-Germanic *Hemina-.Barnhart (1995:357).

Basic concepts

While there are abundant and varied sources for conceptions of Heaven, the typical believer's view appears to depend largely on his religious tradition and particular sect. Some religions conceptualize Heaven as pertaining to some type of peaceful life after death related to the immortality of the soul. Heaven is generally construed as a place of happiness, sometimes eternal happiness. A psychological reading of sacred religious texts across cultures and throughout history would describe it as a term signifying a state of "full aliveness" or wholeness.

In ancient Judaism, the belief in Heaven and afterlife was connected with that of Sheol (mentioned in Isaiah 38:18, Psalms 6:5 and Job 7:7-10). Some scholars asserted that Sheol was an earlier concept, but this theory is not universally held. One later Jewish sect that maintained belief in a Resurrection of the dead was known as the Pharisees. Opposed to them were the Sadducees who denied the doctrine of Resurrection (Matt. 22:23). In most forms of Christianity, belief in the afterlife is professed in the major Creeds, such as the Nicene Creed, which states: "We look for the resurrection of the dead, and the life of the world to come."

Examples of the different terminology referencing the concept of "heaven", in the Christian Bible are:

the kingdom of heaven (Matthew 5:3), the kingdom of the Father (Matthew 13:43), life (Matthew 7:14), life everlasting (Matthew 19:16), the joy of the Lord (Matthew 25:21), great reward (Matthew 5:12), the kingdom of God (Mark 9:45), the kingdom of Christ (Luke 22:30), the house of the Father (John 14:2), city of God, the heavenly Jerusalem (Hebr., xii), the holy place (Hebrews 9:12; D. V. holies), paradise (2 Corinthians 12:4), incorruptible crown (1 Corinthians 9:25), crown of life (James 1:12), crown of justice (II Timothy iv, 8), crown of glory (1 Peter 5:4)

In Buddhism there are several heavens, all of which are still part of Samsara (illusionary reality). Those who accumulate good karma may be reborn in one of them. However, their stay in the heaven is not eternal—eventually they will use up their good karma and will undergo a different rebirth into another realm, as humans, animals, or other beings. Because Heaven is temporary and part of Samsara, Buddhists focus more on escaping the cycle of rebirth and reaching enlightenment (Nirvana). In the native Chinese Confucian traditions Heaven (Tian) is an important concept, where the ancestors reside and from which emperors drew their mandate to rule in their dynastic propaganda, for example.
