You see the separation of life as very arbitrary at this time. You are not alone in this assumption. You have far more connection than you are even vaguely aware of. You will not lose the love that is yours.
Love is its own reward. We do not have to worry about what other people think about us. We can never feel alone or isolated when we understand that it is impossible for love to leave our side. Love is all around us.
Spiritual principles, if true, are true for everyone. That is the yardstick that validates their authenticity. Authentic spiritual ideas also have the universal power to heal. Healing is the building block of both individual and collective spiritual evolution.
That voice you listen to is no friend. It promises so much but when has it ever given you what it promised? When has it ever given you any happiness longer than a fleeting moment? It has your destruction as its goal, not your happiness.
