Amrita (Sanskrit: अमृत, IAST: amṛta), Amrit or Amata in Pali, (also called Sudha, Amiy, Ami) is a Sanskrit word that means "immortality". It is a central concept within Indian religions and is often referred to in ancient Indian texts as an elixir. Its first occurrence is in the Rigveda, where it is considered one of several synonyms for soma, the drink of the Devas. Amrita plays a significant role in the Samudra manthan, and is the cause of the conflict between Devas and Asuras competing for amrita to obtain immortality.
Amrita has varying significance in different Indian religions. The word Amrit is also a common first name for Sikhs and Hindus, while its feminine form is Amritā. Amrita is cognate to and shares many similarities with ambrosia; both originated from a common Proto-Indo-European source.
Amrita is composed of the negative prefix, अ a from Sanskrit meaning 'not', and mṛtyu meaning 'death' in Sanskrit, thus meaning 'not death' or 'immortal/deathless'.
The concept of an immortality drink is attested in at least two ancient Indo-European languages: Ancient Greek and Sanskrit. The Greek ἀμβροσία (ambrosia) is semantically linked to the Sanskrit अमृत (amṛta) as both words denote a drink or food that gods use to achieve immortality. The two words appear to be derived from the same Indo-European form *ṇ-mṛ-tós, "un-dying" (n-: negative prefix from which the prefix a- in both Greek and Sanskrit are derived; mṛ: zero grade of *mer-, "to die"; and -to-: adjectival suffix). A semantically similar etymology exists for Greek nectar, the beverage of the gods (Greek: νέκταρ néktar) presumed to be a compound of the PIE roots *nek-, "death", and -*tar, "overcoming".
Amrita is repeatedly referred to as the drink of the devas, which grants them immortality. Despite this, the nectar does not actually offer true immortality. Instead, by partaking it, the devas were able to attain a higher level of knowledge and power, which they had lost due to the curse of Sage Durvasa, as described in the samudra manthana legend. It tells how the devas, after the curse, begin to lose their immortality. Assisted by their rivals, the asuras, the devas begin to churn the ocean, releasing (among other extraordinary objects and beings) the amrita.
In Sikhism, amrit (Punjabi: ਅੰਮ੍ਰਿਤ) is the name of the holy water used in Amrit Sanchar, a ceremony which resembles baptism. This ceremony is observed to initiate the Sikhs into the Khalsa and requires drinking amrit. This is created by mixing a number of soluble ingredients, including sugar, and is then rolled with a khanda with the accompaniment of scriptural recitation of five sacred verses.
Metaphorically, God's name is also referred to as a nectar:
ਅੰਮ੍ਰਿਤ ਸਬਦੁ ਅੰਮ੍ਰਿਤ ਹਰਿ ਬਾਣੀ ॥
Amrit sabad amrit hari bāṇī.
The Shabda is Amrit; the Lord's bani is Amrit.
ਸਤਿਗੁਰਿ ਸੇਵਿਐ ਰਿਦੈ ਸਮਾਣੀ ॥
Satiguri sēviai ridai samāṇī.
Serving the True Guru, it permeates the heart.
ਨਾਨਕ ਅੰਮ੍ਰਿਤ ਨਾਮੁ ਸਦਾ ਸੁਖਦਾਤਾ ਪੀ ਅੰਮ੍ਰਿਤੁ ਸਭ ਭੁਖ ਲਹਿ ਜਾਵਣਿਆ ॥
Nānak amrit nāmu sadā sukhdātā pī amritu sabha bhukh lahi jāvaṇiā.
O Nanak, the Ambrosial Naam is forever the Giver of peace; drinking in this Amrit, all hunger is satisfied.
Buddha is called as "Amata Santam" in Pali Literature.
According to Thanissaro Bhikkhu, "the deathless" refers to the deathless dimension of the mind which is dwelled in permanently after nibbana.
In the Amata Sutta, the Buddha advises monks to stay with the four Satipatthana: "Monks, remain with your minds well-established in these four establishings of mindfulness. Don't let the deathless be lost to you."
In the questions for Nagasena, King Milinda asks for evidence that the Buddha once lived, wherein Nagasena describes evidence of the Dhamma in a simile:
"Revered Nagasena, what is the nectar shop of the Buddha, the Blessed One?"
"Nectar, sire, has been pointed out by the Blessed One. With this nectar the Blessed One sprinkles the world with the devas; when the devas and the humans have been sprinkled with this nectar, they are set free from birth, aging, disease, death, sorrow, lamentation, pain, grief and despair. What is this nectar? It is mindfulness occupied with the body. And this too, sire, was said by the Blessed One: 'Monks, they partake of nectar (the deathless) who partake of mindfulness that is occupied with the body.' This, sire, is called the Blessed One's nectar shop."

Chinese Buddhism describes Amrita (Chinese: 甘露; pinyin: gānlù) as blessed water, food, or other consumable objects often produced through merits of chanting mantras.
Amrita (Tibetan: བདུད་རྩི་, Wylie: bdud rtsi, THL: dütsi) also plays a significant role in Vajrayana Buddhism as a sacramental drink which is consumed at the beginning of all important rituals such as the abhisheka, ganachakra, and homa. In the Tibetan tradition, dütsi is made during drubchens – lengthy ceremonies involving many high lamas. It usually takes the form of small, dark-brown grains that are taken with water, or dissolved in very weak solutions of alcohol and is said to improve physical and spiritual well-being.
The foundational text of traditional Tibetan medicine, the Four Tantras, is also known by the name The Heart of Amrita (Wylie: snying po bsdus pa).
The Immaculate Crystal Garland (Wylie: dri med zhal phreng) describes the origin of amrita in a version of the samudra manthana legend retold in Buddhist terms. In this Vajrayana version, the monster Rahu steals the amrita and is blasted by Vajrapani's thunderbolt. As Rahu has already drunk the amrita he cannot die, but his blood, dripping onto the surface of this earth, causes all kinds of medicinal plants to grow. At the behest of all the Buddhas, Vajrapani reassembles Rahu who eventually becomes a protector of Buddhism according to the Nyingma school of Tibetan Buddhism.
Inner Offering (Wylie: Nang chod, Chinese: 内供) is the most symbolic amrita offering assembly, and the Inner Offering Nectar Pill (Wylie: Nang chod bdud rtsi rilbu, Chinese: 内供甘露丸) is a precious and secret medicine of Tibetan Buddhism, which are only used internally for higher ranking monks in Nyingma school. Its ingredients including Five Amrita and Five Meat, which represents five buddha, and five elements respectively. According to Tantras of Chakravarti, and Tantras of Vajravārāhī, a ceremony needs to be held for melting and blessing the Inner Offering Nectar. Five Nectar needs to be arranged in four directions: yellow excrement in the east, green bone marrow in the north, white semen in the west and red blood in the south, blue urine is placed in the center. Four Nectar should come from wise monks and the ova should be collected from the first menstruation of a blessed woman. The Five Meats are arranged similarly, meat of black bull in the southeast, the meat of the blue dog in the southwest, the meat of the white elephant in the northwest, the meat of the green horse in the northeast, and the meat of a red human corpse in the center. After the ceremony, these ingredients will transform into a one taste (ekarasa) elixir, which bestows bliss, vitality, immortality and wisdom. Actual modern practitioner will take a 'synthesized essence' of the Nectar Pill and combined it with black tea or alcohol, but mostly the "Nectar Pill" are derived from plants.
