sita-ram, radha-krishna, laxmi-vishnu but why "Shiv - Shakti"
because Shiv is supreme and his opposite power is Shakti
" vishnu is treated as a cheater by "rakshas" but not Shiva"
"Shiva drank the poison when everybody was afraid included vishnu"
"Shiva is worshiped by everybody no matter he is rakshas or devta"
"In Mahabharat muni vyas says to Ashwathama that both Nar (arjun) and Narayana (krishan) have power from Lord Shiva so they are invinsible only Shiva can defeat them" (this is asked by Ashwathama when his Brahmastra has no effect over them)
Deside yourself who is supreme.
