who killed narakasura lord krishna or satyabhama?

A) Satyabhama devi defeated narakasura in the furious war but later lord sri krishna killed narakasura by chakraayudha, actually narakasura is the son of lord varaha and bhudevi but the lawfull act of lord sri hari should be noted. our all-mighty lord sri hari doesn't spare any one who destroys dharma or sajjanas though the person be his own son but dharma is most preferred  than any relations in the world. ,
let us celebrate the victory of divinity over demonity , victory of dharma over adharma, victory of light over darkness, victory of good over bad.
happy deepavali

how the karmas are cleansed?

 A) We clean our body with water, we clean our tongue by speaking divine words or mantras, we clean our mind by listening to the lord sri hari's mahimas and dharmic topics, we clean our karmas by doing samamrpana to sri hari by saying sri krishnarpanamastu. (bhagavta uddhava geeta)

As i was in badari yatra i was unable to update my blog for all these days. any how with hari vayu gurugala anugraha completed badari yatra successfully along with my vidya guru sri uttaradimathadhisha sri 1008 sri satyatma tirtha swamiji.
sri madhwacharya reminds us the greatness of badari,ganga and sri madhwa shastra (dvaita siddhantha).
नेदृशं स्थलमलं शमलघ्नं नास्य तीर्थसलिलस्य समं वाः ।
नास्ति विष्णुसदृशं ननु दैवं नास्मदुक्तिसदृशं हितरूपम् ।। (सुमध्व विजयः)
there is no pious place in the world than badari which destroys all our sins ,  no other pure water as ganges, there is no other supreme thing than sri hari in whole 14 worlds, there is no other philosophical divine teachings other than sri madhwacharya's words in the whole world.
Be proud to be a maadhwite.(madhwacharya's disciple)
