Aupasana (औपासनः)

Aupasana (Samskrit : औपासनः) is one of the important Smarta Yajnas performed daily by grihasthas who have been initiated during marriage. Aupasana, which must be performed every day, is commenced in the Grhyagni (Aupasanagni) and it must be preserved throughout one's life. The seven pakayajnas, rites including upanayana and shraaddha, must be conducted in the aupasana fire.

Smarta Karma

All rites in which the aupasana fire is used and pertain to an individual and his family are "Grhyakarmas". They are related exclusively to the family and are not very elaborate. Even so they are conducive to the good of the world outside also. Grhyasutras deal with such rites. They belong to the Smritis and so are called "Smarta-karmas". The seven Pakayajnas also belong to this category.

The list of seven Pakayajnas according to Apastamba Grhyasutras as elucidated in the commentary of Haradatta, include

तत्र च सप्त पाकयज्ञसंस्थाः - औपासनहोमो, वैश्वदेवं, पार्वण, मष्टका, मासिश्राद्धं, सर्पबलिं, रीशानबलिरिति ।

• Aupasanahoma
• Vaishvadeva
• Parvana
• Ashtaka
• Masishraddha
• Sarpabali
• Ishanabali

Other versions of Grhyasutras are present. For example: according to Baudhayana Grhya sutras, the Pakayajnas are

• Huta 
• Prahuta 
• Ahuta 
• Shulagava 
• Baliharana 
• Pratyavarohana 
• Ashtakahoma

औपासनः ॥ Aupasana

Aupasana can be considered as a enhancement of samidadhanam which is performed by brahmacharis once initiated by Upanayana ceremony.

Etymology

According to Vachaspatyam Aupasana is given as

उपास्यते प्रतिदिनमित्युपासनो गृह्योऽग्निस्तत्र भवः अण् । गृह्याग्नौ कर्त्तव्ये सायंप्रातर्होमादौ कर्म्मणि । गृह्याग्निश्च विवाहाग्निः ।

That Agni which is worshipped at home everyday, Grhyagni in which the morning and evening homa kriyas are to be performed. Grhyagni is Vivahagni.

Initiation into Aupasana

During vivaha samskara one is initiated to enter the grhasta ashram by setting up the आवसथ्याग्निः ॥ Avasatyaagni to the north of the vedi. (Paaraskara Grhya Sutra Adhyaya 1 Kandika 2 Mantra 1)

आवसथ्याधानं दारकाले १ दायाद्यकाल एकेषाम् २ ॥ āvasathyādhānaṁ dārakālē 1 dāyādyakāla ēkēṣām 2 (Para.Grhy.Sutra. 1.2.1)

Meaning : The setting up of Aavasatya agni is (performed) at the time of wedding. At the time of inheritance according to some.

Aupasanagni

The son lights his aupasana fire during his marriage from his father's aupasana fire. The son's aupasana fire, like his father's must be maintained throughout his life. Thus, without any break, the sacred fire is kept burning in the family generation after generation.

Normally this fire is located in the north of the hall which accommodates the other Agnikundas . Yajnakunda for this Agni may be circular or square

Aupasana Vidhi

During marriage a person receives additional instructions to perform nityakarma. A few features of Aupasana include

• Starting from marriage, a grihasta (along with his wife) offers yava or rice aahutis twice daily at twilight time (dawn and dusk) in the Aupasanagni, this is also called as Aupasana.
• All the daily ahutis and cooking involves the aupasana fire and pertain exclusively to the individual and his family. Thus, "Grhyakarmas" including the seven pakayajnas involve the aupasana agni or Grhyagni or smarthagani. They are related exclusively to the family and are not very elaborate.
• Aupasana is to be performed by the grihasthas of the three varnas. Valmiki Ramayana in Ayodhya kanda mentions that Sri Ramachandra, a kshatriya, enquires Bharata about tending the Agni in the house.

  कच्चिद् अग्निषु ते युक्तो विधिज्नो मतिमान् ऋजुः | हुतम् च होष्यमाणम् च काले वेदयते सदा || २-१००-१२ (Valm. Rama. 2.100.12)

  Meaning : "I hope that a brahmin who is versed in the traditions, who is intelligent and just, employed in your sacred fires, always informs you in time, about a sacrificial fire having been or going to be fed with oblations."
• Every grihastha has to maintain the agni until he is prevented by old age or illness or death. In case where he cannot perform it on behalf of him his son, brother or son-in-law may perform the ritual.
• Anuditahomi's perform aupasana homa before sunrise and Uditahomi's perform it after sunset.
• Mantras for conducting Agnihotra are according to the Sutras in particular shaka of the Veda of the Karta.
• Samidhas for homa are smaller and different from those used in Srauta yajnas. However, the trees that they are collected from are the same as those in yajnas. They should be covered with bark, of proper shape, of same dimensions, dried form, of the girth of the index figure, unbroken, not with two branches, not contain worms or green leaves and be strong.

समिधःपावनाः पूज्याः चर्मयुक्ताः परात्पराः | युष्मान् हरामि होमार्थं अस्मान् रक्षत सर्वदा ॥

• Morning aahutis are made to the deities Surya and Prajapati, while the evening aahutis are made to Agni and Prajapati.

• Nitya agnihotra is not to be performed by an uninitiated bachelor or widows.
