Why are people relating love with heart, Why not brain?

Brain thinks.

Heart feels.

You cannot keep “thinking” about love, you want to “feel” love.

Feelings are subtler than thoughts.

Brain/ Mind is more on intellectual level. It strikes deals, contracts, does business, Analyszes things, It is sensible etc - Love knows none of these

Heart has feelings, hearts has emotions, it is sensitive. Love is an expert in feelings, emotions, being sensitive…

Therefore love is more of a subject of heart than the brain.
