When someone whose heart is troubled and worried, out of true affection and kindness, told “Relax, don’t worry,” this statement helps and can make a big difference. Telling someone to let go and relax can instil a sense of peace. This holds true not only for human beings but also for animals. When you show a genuinely loving expression on your face and kindly stroke an animal with your hand, these actions help it to feel at ease. Most important is to behave with love and compassion, expressing these feelings by being gentle and affectionate.
