Source Status

The text bearing the number Toh 1990 in the Tibetan Tengyur currently has no recorded title; both the Vietnamese title and the English title are listed as “Untitled.” This is not an uncommon case in the Tengyur collection, where certain commentaries, rites of confession, or brief practice texts have been transmitted without a complete title, or where the original title has been lost over time through repeated copying. The technical identifying code for this entry, vajravarahisadhana, suggests that the content may be related to a sādhana, or practice liturgy, of Vajravārāhī, yet this is only a clue from the internal identifying string and has not been confirmed from the actual full text.

Since the source text has not yet been fully collated and verified, this exposition can present only general context and potential significance for study and practice on the basis of the tradition to which the text belongs.

Context

The Tengyur (bsTan 'gyur) is the second part of the Tibetan Buddhist Canon, comprising thousands of commentarial texts, annotations, sādhanas (practice liturgies), stotras (hymns of praise), and secondary tantras, chiefly works by Indian and Tibetan masters translated into Tibetan. Unlike the Kangyur (bKa' 'gyur), which contains teachings directly attributed to the Buddha, the Tengyur is the treasury of commentaries and treatises by scholars and holy practitioners who vowed to transmit the Dharma.

Number Toh 1990 belongs to the Treatise section of the Tengyur (tengyur-shastras), a broad classification that ranges from extensive philosophical treatises to concise practice texts. Based on the identifying code vajravarahisadhana, this text may be situated within the Vajrayāna tantric lineage, specifically among practices connected with one of the most important feminine manifestations in the Tibetan tantric tradition.

Content That May Be Identified from the Descriptive Information

From the identifying code vajravarahisadhana, it may be understood that this text, though its official title has not been confirmed, most likely belongs to the genre of sādhana (practice liturgy), namely instructions for meditative practice combining visualization of the form of the yidam deity, mantra recitation, and rituals of offering or accomplishment.

Vajravārāhī (Tibetan: rDo rje phag mo) is a feminine yidam deity of the tantric lineage, widely revered in the Kagyu, Sakya, and Nyingma traditions of Tibetan Buddhism. The title “Vajravārāhī” combines two elements: vajra (diamond or adamantine, symbolizing the indestructible and utterly pure nature of awakening) and vārāhī (connected with the symbol of the sow, representing the power to transform ignorance). She is often described in a dynamic state, expressing the union of great bliss (mahāsukha) and emptiness (śūnyatā), the two core pillars of the supreme tantric path.

If Toh 1990 is indeed a sādhana of Vajravārāhī, it may include elements such as visualization of the yidam’s form, establishment of the inner mandala, recitation of the root mantra, practices of purification and accumulation of merit and wisdom, together with prayers of dedication. However, this is only an assessment based on genre and traditional characteristics; specific details cannot be asserted when the full text has not been accessed.

Significance for Study and Practice

Although the specific text has not been fully confirmed, studying and encountering sādhanas in the tantric tradition offers many profound values for practice:

First, sādhana liturgies are not merely external rituals, but comprehensive means for transforming body, speech, and mind. The practice of visualizing the yidam is a way for the practitioner to connect with the qualities of awakening latent within one’s own mind, gradually recognizing that the yidam and one’s own mind are not two.

Second, receiving, studying, and practicing sādhana in the tantric tradition always requires a foundation in lineage transmission: the practitioner must receive empowerment (abhiṣeka), oral transmission (lung), and explanation (tri) from a realized teacher belonging to an authentic lineage before entering into the practice.

Third, texts such as Toh 1990 remind us that the treasury of Mahayana and tantric Dharma is immensely rich, and that many precious fragments still await further study, translation, and clarification for Buddhist students today.
