Chamakam
Source : Kanchikamakoti Peetham चमकम् CHAMAKAM अग्नाविष्णू सजोषसेमा वर्धन्तु वां गिरः । द्युम्नैर्वाजेभिरागतम् ॥ Kalpam: After chanting the mantra अग्नाविष्णू and performing homam four times with ghee, one should then perform homam in continuous flow, chanting the mantras from वाजश्चमे upto the eleventh Anuvakam at the same time. Here from वाजश्चमे upto the eleventh Anuvakam it is a single mantra. The division into eleven Anuvakams has been done for the purpose of using each Anuvakam as one mantra in karmas like Parayanam, other than Homam. This अग्नाविष्णू mantra alone must be chanted for Chaturgrihita Homam. Meaning: हे अग्नाविष्णू- O Devas Agni and Vishnu! सजोषसा- (Both of you) be kind in the same manner. वां- Spoken about you, इमा गिरः- these words of praise, वर्धन्तु- may grow. द्युम्नैः- With materials (like gold, silver etc.), वाजेभिः- and food items, आगतम्- please come.
