નાગર, નાચણ ને પાવડી, સીંગી ને સુનાર;

nāgara, nācaṇa nē pāvaḍī, sīṁgī nē sunāra;

Literally: A Nagar Brahmin, a dancer, a wooden sandal, a horn-player, and a goldsmith; these five never become one's own, and the sixth is the resident of Kheda.
What it means: Certain classes of people and objects are inherently unreliable and can never be trusted to be truly loyal.
