2.5.1.14

taṃ vai svatavobhya iti kuryāt | svayaṃ hi ta etam bhāgamakurvatoto svatavobhyo yājyānuvākye na vindanti sa u khalu māruta eva syātsa vā eṣa prajābhya evāhiṃsāyai kriyate tasmānmārutaḥ

Let him offer it to the 'self-strong' (Maruts); since they gained that share for themselves. [If], however, they (the priests) do not find an invitatory and an offering prayer (addressed) to the 'self-strong' (Maruts), let it be (offered) simply to the Maruts. It is offered for the safety of creatures: hence it is offered to the Maruts.
