They are most delightful to utter.
Hear and remember and are dear as Rama and Laxmana to Tulsidas,
When treated separately, the tow letters lose their harmony, are differently pronounced, bear diverse meaning in the form of seed letters and as such yield different results,
Whereas they are naturally allied even as Brahma-the cosmic spirit, and Jiva the individual spirit, good brothers like the divine sages Nara and Narayana, they are sustainer of the universe and redeemers of the devotees in particular,
May Lord Bless all
Thanks please
