What is the subtle difference between Mahavira's transcendence of attachment, Christ's holy indifference, Buddha's indifference, and Krishna's non-attachment, and in what way are they the same?

According to Osho, all four aim at freedom from the world’s entanglements—the same summit—but their flavors differ: Christ’s neutrality tends toward sadness and occasional choosing; Buddha’s indifference is silent, choiceless peace; Krishna’s non-attachment flows singing and dancing; Mahavira’s transcendence carries a secret bliss. Thus methods and moods diverge, while the realized distance from attachment is one.
