The River Cannot Go Back

I am entering into this vast ocean right now. I usually don't add people on Facebook if I don't know them but since I started the Buddhist path and listening/meditating Buddha's teachings about having a open heart I am trying to check my own fear. It's opposite to what I learned from my culture conditioning. I was taught not to trust strangers. But if I have to move forward on this path I need to cultivate a loving kindness heart for all beings without any judgements and exceptions. I am still not sure if it's ok? But I need to take this risk so I can become a part of this ocean and lose this mind made Self.
May all beings be peaceful 🙏🏽
