Fondness, affection, the intimacy that grows from familiarity and attachment.
Literally: affection, fondness, intimacy
Ulfat is affection — the warm, settled fondness and intimacy that grows between two hearts, gentler and more companionable than the burning ishq. It is love as closeness and familiarity, the bond that ripens with time and nearness. Where ishq scorches, ulfat warms; the ghazal uses it for the tender attachment that underlies passion, the quiet love within the loud one.
