*matsya uvāca
hanta te kathayiṣyāmi pitṝṇāṃ vaṃśamuttamam
svarge pitṛgaṇāḥ sapta trayasteṣāmamūrtayaḥ //

The God Fish replied that, out of the seven groups of the Pitṛis residing in Heaven, the Pitṛis belonging to three particular groups are without form, (that is composed of intellectual, not elemental, substance), while the Pitṛis of the remaining four groups have form (i.e., corporeal). The formless ones are the Pitṛis of Prajâpati Vairâja.—(2-3).
