જેને રાખું બગલમાં, તેજ વેરી હોય; ચંદન રૂએ સાસે ભર્યો, મારૂં સગું ન હોય.

jēnē rākhuṁ bagalamāṁ, tēja vērī hōya; caṁdana rūē sāsē bharyō, mārūṁ saguṁ na hōya.

Literally: The one I keep under my armpit turns out to be the enemy; sandalwood weeps with heavy sighs, saying 'no one is my relative.'
What it means: Those whom we protect and keep closest to us are often the ones who betray us.
