Twilight language
Secret language of tantric traditions

Twilight language or secret language is a rendering of the Sanskrit term sāṃdhyābhāṣā (written also sāndhyābhāṣā, sāṃdhyabhāṣā, sāndhyabhāṣā; Wylie: dgongs-pa'i skad, THL gongpé ké) or of their modern Indic equivalents (especially in Bengali, Odia, Assamese, Maithili, Hindi, Nepali, Braj Bhasha and Khariboli).
As popularized by Roderick Bucknell and Martin Stuart-Fox in The Twilight Language: Explorations in Buddhist Meditation and Symbolism in 1986, the notion of "twilight language" is a supposed polysemic language and communication system associated with tantric traditions in Vajrayana Buddhism and Hinduism. It includes visual communication, verbal communication and nonverbal communication. Tantric texts are often written in a form of the twilight language that is incomprehensible to the uninitiated reader. As part of an esoteric tradition of initiation, the texts are not to be employed by those without an experienced guide and the use of the twilight language ensures that the uninitiated do not easily gain access to the knowledge contained in these works.
The phrase "twilight language" has subsequently been adopted by some other Western writers, including Judith Simmer-Brown.
Meaning
According to Mircea Eliade (1970), in 1916 Hara Prasad Shastri proposed the translation of "twilight language". However, in 1928 Vidhushekar Shāstri disagreed with that translation, showing that the term is based on a shortened form of the word sandhāya, which can be translated as "having in view", "intending", or "with regard to". Eliade concludes that: "Hence there is no reference to the idea of a 'twilight language'." He continues by speculating on how the term came to be corrupted by scribes who read the familiar word sandhyā ("crepuscular") for the original sandhā. Eliade therefore translates the phrase as "intentional language".
This brief starts where responsible research should: with the source description of “Twilight language” as secret language of tantric traditions. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as secret language of tantric traditions. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 20, 2026. The linked authority identifier is Q3471834. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1986, 1970, 1916 and 1928.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
