Some remarks on the possible methods of composing saṃhitās as hinted in chosen texts belonging to the Pāñcarātra school are presented in “Sect. 1”. In “Sect. 2,” the content and the structure of the Sātvatasaṃhitā and Īśvarasaṃhitā are compared. In fact, both texts are independent works even though in the light of some Pāñcarātrika texts they are considered to be mutually linked, the latter being considered a “commentary” of the former. In “Sect. 3,” the initiation as found in both texts (...) is outlined. In “Sect. 4”, I focus on the re-use of the portions concerning dīkṣā: although the redactor of the Īśvarasaṃhitā borrowed almost all the Sātvatasaṃhitā’s chapters on initiation, he dealt in a very different way with the practice called vaibhavīyanarasiṃhakalpa that in the context of the latter text plays the role of a unique preliminary purification. Strikingly, the Sātvatasaṃhitā’s redactor re-used the initial verses describing the vaibhavīyanarasiṃhakalpa, putting them into other contexts, not necessarily connected to the issue of initiation, whereas he totally omitted its impressive section concerning magical powers.
