Traditionally, the Korika is meant to be received via Guru-mukha (from the mouth of a teacher). Many modern Tantric teachers (e.g., Rajarshi Nandy or the Sri Vidya lineage) offer PDFs of the Korika to their disciples upon Diksha (initiation). This is the most authentic route.
Scribd is a tool for access; a Guru is a tool for salvation. Do not confuse the two.
