Five things for equanimity to grow: 1. Impartiality regarding all living and sentient beings 2. Indifference regarding all inanimate constructions 3. Avoiding biased people who prefer favouritism and one-sided partiality 4. Friendship with well ballanced people unmoved by both pleasure and pain 5. Commitment to ballance the mind into even and imperturbable equanimity (from Samyutta Nikaya 46)
