A sub-type of Antarāya (obstructive) Karma, by the Udaya (rise) of which, inspite of availability of materials, a person cannot offer anything to the person who, being possessed of the traits of ascetics, is fit to be given (though he is present) and inspite of having the knowledge about the great reward of giving Dāna (offering food etc. to the ascetics), he does not have any enthusiasm for giving Dāna.
yadndayavaśāt sati vibhave samāgate ca guṇavati pātre dattamasmai mahāphalamiti jānannapi dātuṃ notsahate taddānāntarāyam.
(Prajnā 23.59 Vṛ Pa 475)
