Ghazal after a long time

I learnt a ghazal last night. Kitni Raahat Hai - Shamim Jaipuri's lyrics. Sung by Mohammed Rafi. Learning and singing has left me feeling extremely fulfilled. I wish I could identify that raagam. It sounds like valachi sa ga pa da ni sa. An occasional pratimadhyamam. The presence of another swaram is a bit elusive. Giving a vivaadi effect. Not sure. It is the sort of ghazal that might play on the radio in the middle of afternoon or late night when activity slows, drowsiness envelopes and the wind silent. And I am at rest with eyes closed, receiving the gentle melody.
