Featured article

The Mahānirvāṇa Tantra (Sanskrit महानिर्वाणतन्त्रम्‌, "Tantra of the Great Liberation") is a Sanskrit Tantric scripture of the Śākta tradition, cast as a dialogue between Śiva and Pārvatī and divided into fourteen chapters (ullāsa). It is one of the most widely cited Tantric texts to record the ritual use of cannabis, under the Sanskrit name vijayā (विजया), which the standard commentary glosses explicitly as bhaṅgā (भङ्गा).

The cannabis material occupies a small but tightly framed sequence in the fifth chapter (Pañcamollāsaḥ), where the goddess is offered vijayā as a sanctified substance within the pañca-tattva ritual. The text supplies a purification mantra, an offering procedure and a prescription for the practitioner to consume the bhaṅgā from the left palm following the worship. The commentary by Hariharānanda Bhāratī, the sannyasi associated with the early Bengali Tantric revival of the late 18th and early 19th century, is the standard interpretive layer transmitted with the printed Sanskrit text and the one used in Avalon's English translation. read more →

Comparison of self-pollination and intercrossing for feminized seed production in Thai Hang Kra Rok cannabis (Cannabis sativa L.) landrace

Compares selfing with intercrossing for producing feminized seed from two Thai landrace accessions of Hang Kra Rok cannabis, one from Bangkok and one from Sakon Nakhon. Female cuttings were treated with colloidal silver to induce male flowers, and the progeny were grown in a plant factory with artificial lighting. Both selfed lines and the Sakon Nakhon by Bangkok cross gave 100% female plants, while the reciprocal cross produced one hermaphrodite (5.6%). Dry inflorescence weight did not differ between treatments, and the Bangkok selfed line had the highest THC content at 6.58%. The plants were grown under artificial light, so the chemistry is not field chemistry.
