મુખ મીઠાં મનમાં કપટ, સ્વાર્થ લગી સગાહ છે,

mukha mīṭhāṁ manamāṁ kapaṭa, svārtha lagī sagāha chē,

Literally: Sweet-mouthed with deceit in the heart, companionship lasts only till self-interest,
What it means: Selfish friends maintain friendly ties only as long as they serve their own personal gain.
