SAU SAKHI (lit. a book of one hundred anecdotes) is the popular name of Gur Ratan Mal (lit. a string of the Guru`s gems), a work esoteric and prophetic in nature : also problematic as regards the authenticity of its text. Its writer, one Sahib Singh, describes himself only as a scribe who wrote to the dictation of Bhai Gurbakhsh Singh, better known as Bhai Ram Kunvar (1672-1761) and a knowledgeable and honoured member of the retinue of Guru Gobind Singh (1666-1708). The book is meant to be a narrative pertaining to the life of Guru Gobind Singh, supposedly based on the personal knowledge of Bhai Ram Kunvar, although later interpolations and corruption of the text are clearly decipherable.
TIKA, derived from the root tik, a loan word from the aboriginal languages, meaning `to mark` or `to explain`, signifies commentary, exegesis or explanation, especially of a scriptural text. Originally meant to provide a simple paraphrase of the spiritual and mystical revelations, a tika may now embrace an exhaustive analysis and interpretation of the text. Such tikas and commentaries have been part of the Indian religious tradition since ancient times.In tracing the history, reference is made to Yaska Muni (circa 700 BC) who mentions in his Nirukta numerous preceding commentators of the sacred scriptures.
