PRĪKHIĀ PRAKARAṆ (prīkhiā = test; prakaraṇ = part or fragment) by Paṇḍit Tārā Siṅgh Narotam is a small tract, bound with the author's more famous Gurumat Nirṇaya Sāgar, endevouring to establish the authenticity or otherwise of the authorship of the various Sikh texts including the Gurū Granth Sāhib, the Dasam Granth, Prāṇ Saṅglī, Janam Sākhī Bhāī Bālā, Prem Sumārag, Makke dī Goṣṭi, Vārāṅ by Bhāī Gurdās, hukamnāmās, etc. He analyses the texts of these volumes and determines the authorship of each on the basis of internal evidence. A text which has either the signature or stamp of the Gurūs or came into vogue in their time is considered authentic. The entire Gurū Granth Sāhib as well as the Dasam Granth is authentic, but Nasīhat Nāmah, attributed to Gurū Nānak, and Prem Sumārag to Gurū Gobind Siṅgh are pronounced apocryphal works. Similarly, Tārā Siṅgh delcares that Sarab Loh, Paintīs Achharī, Mukti Mārg, Chhakkā, Sākhī Gurbakhsh Siṅgh are not the works of Gurū Gobind Siṅgh.
