By Swami Harshananda
Sometimes transliterated as: Upasthana, UpasthAna, Upasthaana
Upasthāna literally means ‘worship or homage’.
An āhitāgni is expected to perform Agnihotra both in the morning and in the evening. After the evening offering, he is expected to pay homage to the fire by reciting the Vātsapra mantras. This is called upasthāna. Different views are presented for whether this upasthāna should be done only in the evening or both in the morning and in the evening.
