A 'Sâdhana' is an instrument that leads to a particular goal. In Tantra, it is a technical term denoting worship or spiritual practice. This is a collection of related instructional papers designed to aid the aspirant through a foundation practice. The work was originally conceived as leading to a practice over the course of one lunar month. In addition, the author had added several useful appendices including the previously unpublished Tantrik Knuckle Bone Oracle. The reader might find this a good general primer combined with some more unusual, perhaps advanced material.
