Skanda Purana — Mahesvara Khanda, Shloka 18
नैवेद्यं हविषश्चैव यज्ञोऽयं हि विकल्मषः । स एव यज्ञः प्रोक्तो वै येन तुष्यन्ति देवताः
naivedyaṃ haviṣaścaiva yajño'yaṃ hi vikalmaṣaḥ | sa eva yajñaḥ prokto vai yena tuṣyanti devatāḥ
食供（naivedya）与火供供品（havis）亦在其中——此祭祀确实清净无垢。唯有能令诸天真正欢喜满足者，方称为“牺牲（yajña）”。
Sūta (Lomaharṣaṇa) narrating within Māheśvara-khaṇḍa context
Scene: A clean altar with a small homa-fire; a devotee presents naivedya on a leaf-plate and pours havis into the flame; devas are implied as satisfied through a haloed, unseen presence; prasāda is later shared.
FAQs
