।।4.24।। अर्पण (अर्थात् अर्पण करने का साधन श्रुवा) ब्रह्म है और हवि (शाकल्य अथवा हवन करने योग्य द्रव्य) भी ब्रह्म है ब्रह्मरूप अग्नि में ब्रह्मरूप कर्ता के द्वारा जो हवन किया गया है वह भी ब्रह्म ही है। इस प्रकार ब्रह्मरूप कर्म में समाधिस्थ पुरुष का गन्तव्य भी ब्रह्म ही है।।


Kumara Vaishnava Sampradaya - Commentary
Here the word brahmarpanam means the paraphernalia used to  offer  oblations
in yagna or offering of worship to propitiate  the  Supreme  Lord.  All  the
accessories used  in  yagna  are  also  considered  to  be  Brahman  or  the
spiritual substratum pervading all existence, along with  the  offerings  of
ghee and grain seeds, the fire they are  offered  through  as  well  as  the
performer of the offering.  Lord Krishna is explaining that everything  used
in yagna can be considered as part of the Brahman.  One  who  realises  that
the Brahman or the spiritual substratum pervading all existence is  actually
abiding in all actions reaches the Brahman which is  becoming  cognisant  of
the spiritual substratum of reality underlying and pervading all  existence.
This is the consciousness of the actions  from  an  aspirant  for  moksa  or
liberation where the atma or soul is understood  to  be  non-different  from
the Brahman. Consequently actions performed in this  consciousness  are  all
known to be spiritual and thus realised is in itself a means  for  achieving
atma tattva  or  soul  realisation  thus  precluding  any  further  need  to
practice jnana yoga or cultivation of Vedic knowledge.
