The Buddhist monastic codes (Vinayas) include a provision for a training period of two years for candidates for bhikkhuni ordination. This is one of the few aspects of bhikkhuni ordination that has no parallel in the ordination for monks. The sikkhamana training period is controversial, and is often not followed in modern practice. Santipada undertook a research project to bring together, translate, and analyze the major passages from all Vinayas that deal with the sikkhamana. While incomplete, this project still comprises the largest resource available on this topic.
This project consists of two interconnected websites. Sikkhamana contains mainly comparative tables and analysis, while Bhikkhuni Patimokkha contains translations. Despite its name, the Bhikkhuni Patimokkha site does not include all the Vinaya rules, just the ones relating to the Sikkhamana training.
These sites contain some analysis, but are mostly text and translation. Given the large quantity of material found in all Vinayas, we have presented that material through a variety of comparative tables. The research contained here was fundamental to the work presented in Bhikkhuni Vinaya Studies, especially chapters 6 & 7.
