Adhiṣṭhāna is a term with multiple meanings: seat; basis; substratum; ground; support; and abode. The Monier-Williams Sanskrit-English Dictionary Online holds the following semantic field for adhiṣṭhāna:
Francesca Fremantle gives an etymology of Sanskrit adhiṣṭhāna and Tibetan jinlap: "The Sanskrit word literally means "standing over" and conveys ideas of taking possession, dwelling within, presence, protection, and sovereignty. The Tibetan literally means "an engulfing wave or flood of splendor and power." Dan Martin opines that the Chinese term for adhiṣṭhāna influenced the Tibetan:
points out that in Tibetan Buddhism adhistana blessings are an important part of the pointing-out instruction received from the guru and lineage. Receiving these blessings is dependent on the student having proper motivation, aspiration and intentionality and sufficient "devotion". These blessings may be received from the student's guru during initiation, from the yidam during deity yoga, or simply from being in the presence of holy objects such as a stupa. In a study of the theory and practice of Shingon Buddhism, an extant non-Himalayan school of Vajrayana, Kiyota identifies three kinds of adhiṣṭhāna:
The term adhiṣṭhāna is also used to describe the transformative power of the Buddha. According to D. T. Suzuki:
Stream of blessings
In the Indo-Himalayan lineages of Vajrayana, where traditions of Tantra were introduced in the first wave of translations of Sanskrit texts into Old Tibetan from the 8th century onwards, the term chosen by the community of lotsawa "translators", which importantly is one of the most concerted translation efforts in documented history, chose to render adhiṣṭhāna as. This metaphorical usage of "stream, wave, thread, continuum" is reinforced in philosophy with the mindstream doctrine and its relationship to tantric sādhanā, where it is used in visualizations and invocations, particularly in relation to the Three Vajras of Padmasambhava and depicted in Indo-Tibetan Buddhist and Bon iconography such as representations of the Adi-Buddha and Tapihritsa. Martin Mills, in a modern political and power-relations dissection of jinlap in relation to hierarchical structures of the Gelug, a Sarma school, holds that:
Sadhana
The Prayer of Inspiration known as "The Falling Rain of Blessings"
Honzon Kaji
In Shingon Buddhism, mantras, mudras and visualization practices aim at achievinghonzon kaji or union with the deity. According to Shingon priest Eijun Eidson:
Sarira
or "relics" are held to emanate or inciteadhiṣṭhāna "blessings, grace" within the mindstream and experience of those connected to them.
