According to Osho, the litmus test is joy. True detachment makes you healthier, freer and more loving; joy, freshness, and a spontaneous delight for no reason expand as attachments fall away. Indifference is a counterfeit: it brings dullness, sadness, contraction, and a lifeless control. Track your inner climate: more fragrance, song, and dance means detachment; heaviness and depression signal indifference.
If you feel lighter, happier, and more loving without clinging, that’s detachment; if you feel dull, heavy, and joyless, that’s indifference.
