The above-mentioned reference to the *mangala-sloka* in *Vidyananda's* *Tattvartha-aptamimamsa*, the statement in the *Astasahastree* " *Shastrarambhe'bhishtutasya aptasya mokshamargapranetrutvaya...* ", and the reference in *Apt-pariksha* " *Shrimadtattvarthashadbhutasalilnidheh.... proththanarambhakale 'shastrakarair krtam yat. Stotra...*, *iti tattvarthashastravo munindra stotragochara.* " clearly indicate that they consider the author of the *shastra* to be the one who composed the *mokshamargasya netaram* *stotra*, and by " *shastrakara* " they mean only the author of the *Tattvarth Sutra*, *A. Grdhapichchha*, not *Poojyapada-Devanandi*, the author of *Sarvarthasiddhi*. *Vidyananda* has used the terms " *shastrakara* " and " *sutrakar* " only for the author of the *Tattvarth Sutra* in all his works. Similarly, the terms *Tattvartha*, *Tattvarthashastra*, or *Nishreyasshastra* have also been used only for his *Tattvarth Sutra*, not in a broader or other sense, as we have seen above.
Apart from the above-mentioned references of *Vidyananda*, another very clear and unambiguous reference has been found which attributes the *mangala-sloka* to the *sutrakar* - *Grdhapichchha-Umasvami*. It is as follows: " *Grdhapichchaacharyenaapi tattvarthashastrasyadau 'mokshamargasya netaram' ityadina arhannmaaskarasyaiv parammangalataya prathamamuktatvat.* "
*Go. Ji. Ma. Pra. Ti. Pr. 14*. This reference is from *Siddhantchakravarti Acharya Abhayachandra* (12th-13th century), the author of the *Mandaprabodhika Tika* of the *Gommatasar Jivakanda*, which is seven to eight hundred years old. In it, he has clearly stated that the *mangala-stotra* was composed by *Grdhapichchhaacharya* and that it was composed by him at the beginning of the *Tattvarthashastra* (*Tattvarth Sutra*). He has not called it the *Tattvarthavrittika* of *Poojyapada-Devanandi*. This shows that even seven to eight hundred years ago, the *mangala-stotra* was considered to be the *Tattvarth Sutra* of *Grdhapichchhaacharya*. One more thing to note about this reference is that in ancient times, the *Tattvarthashastra* was referred to as the *Tattvarth Sutra*, and by that, the *Tattvarth Sutra* composed by *Acharya Grdhapichchha* was meant.
