Hence the form kīlaya could mean "you cause to bind/transfix!", or "bind/transfix!". "to bind", while Monier-Williams (285) gives the meanings "to bind, fasten, stake, pin". Indigenous grammar (Pāṇini Dhātupāṭha I.557) gives to Kīl the meaning of bandha, i.e. "Vajrakīlaya" could have come from the second person singular active, causative imperative, of the verb Kīl. It is possible, on the other hand, that the name Vajrakīlaya as favoured by the Tibetans could in fact have been the form that was actually used in the original Indic sources, and that there is no need to hypothesize a correct form "Vajrakīla". Mayer (1996) contests Boord's assertion, pointing out that eminent Sanskritists such as Sakya Pandita employed Vajrakīlaya. The term (vajra)kīlaya is frequently found in Sanskrit texts (as well as in virtually every kīlamantra) legitimately used as the denominative verb 'to spike,' 'transfix,' 'nail down,' etc. This form would have been familiar to them in the simple salutation namo vajrakīlaya (homage to Vajrakīla) from which it could easily be assumed by those unfamiliar with the technicalities of Sanskrit that the name of the deity is Vajrakīlaya instead of Vajrakīla. I suppose this to result from an indiscriminate use by Tibetans of the dative singular kīlaya.

However, as Boord describes it,Īll dictionaries and Sanskrit works agree the word to be kīla (or kīlaka). Bischoff, Charles Hartman and Martin Boord have shown that the Tibetan literature widely asserts that the Sanskrit for their term phurba is kīlaya (with or without the long i).

Most of what is known of the Indian kīla lore has come by way of Tibetan culture. The phurba is associated with the practice of the meditational deity (Sanskrit ishtadevata, Tibetan yidam) Vajrakīlaya (Tibetan Dorje Phurba) or Vajrakīla (वज्रकील). The phurba ( Tibetan: ཕུར་པ or ཕུར་བ, Wylie: phur ba alternate transliterations: phurpa, phurbu, purbha, or phurpu) or kīla ( Sanskrit Devanagari: कील IAST: kīla) is a three-sided peg, stake, knife, or nail-like ritual implement traditionally associated with Indo-Tibetan Buddhism, Bön, and Indian Vedic traditions.
