Metta for a dear person may cause unexpected reactivity such as annoyance, attachment, worry, or irritation. With mindfulness, we can notice when such reactions appear.
The cultivation of metta for a dear person seems easy. However, one must watch out for the ‘hidden’ defilements of either attachment & lust or worry & grief. Hand out as many Metta Candies as possible.
The benefits of pure metta are manifold. Even a short moment of metta is more powerful than a big offering of food. Do not dismiss small acts of kindness.
