Many spiritual teachers focus on the importance of limitless love to God or the Universe before examining other areas.
Here’s an example:
Newborn babies can’t survive without the help of an adult. Babies instinctively seek out their mother’s breasts and find comfort from their parents’ smell because they can’t see quite yet. A baby’s cries can immediately be soothed by a parent’s touch. Cuddling into their parents’ arms brings comfort and security. All of these are very basic feelings necessary for the development of a healthy and happy baby.
Let’s imagine a baby lying in the middle of a bed alone, crying and looking for comfort. The baby cries and no one responds….
Do you think a child who experiences this often would grow up to be happy? Just the opposite. This lonely bed is a good analogy for life and having loving parents is symbolic of having a God in it. Spirituality is a basic requirement for happiness.
When you experience that limitless love and trust for God in your heart, only then will you feel like that comforted newborn baby. You realize this God has accepted you with your flaws and will support you no matter what. And you know what?! It brings you a sense of happiness that comes from the bottom of your heart…. It brings you a sense of security and you are able to fearlessly navigate through your hectic life…. you have a better sense of self-identity and are not afraid of making mistakes because you know the Universe/God will protect you.
That is why your spiritual teachers are truly happy. They lead a solid and blissful life because they feel that limitless love in their hearts and do not feel alone on this big bed called life.
