The people we trust most when we come into the world are our parents. We have unconditional trust in them - that is, up until they destroy it. If you are a parent, please don't do this to your children.
Many people grow up filled with fear. If they do not eat their dinner they are reprimanded, if they break something by accident, they are yelled at, if they lose something they are punished, if they venture into something out of curiosity, they are banished into their room for hours, and when they express themselves, they are hit. It is no surprise that these people may not trust anyone in their early childhood. Which could explain why such people feel and act like lone wolves.
At a young age, if the person you trust the most shatters your trust, it is easy to understand how you can lose trust in everything else and in all others. Even if one parent tries their best to create an environment of love and mask the fear, your trust in their ability to protect you may not last indefinitely.
However, in relationships, love, business and life you need to let your guard down, and this can be challenging at the start. However, through self enquiry, healing and finding your inner child, you can shed layers of distrust. And when you open that door, you will find it less scary than you thought, and it so often generally feels refreshing being more open. You will even trust yourself more. This means that you do not doubt your decisions and listen to your intuition. You learn to trust your gut, and also recognise that when you don't trust it, things often go wrong.
Trust is at the core of everything. Trust in yourself, in your calling, in the world around you, ad in the universe.
Together with the traditional four elements of true love, namely: loving kindness, compassion, joy and equanimity, there are two more elements: respect and trust, which are found in the four, but it helps to mention them. When you love someone, you have to have trust and confidence. Love without trust is not yet love.
Of course, it goes without saying that you have to have trust, respect and confidence in yourself. Trust that you have a good and compassionate nature. You are part of the universe; you are made of stars. When you look at another person, see that s/he is also made of stars and carries eternity within their genes. When you look this way, you naturally feel reverence. True love cannot be without trust and respect for yourself and the other person.
