Love that you feel in your heart is the connection with the loved one. Whenever you think of the loved one and feel love in your heart you are actually communicating with the loved one. You are perceiving the communication as love vibration.

Communication does not need to be in a form of verbal interactions. Love is a language of no word, a means of communication through one’s heart. It is an actual language.

Mind perceives things as separate, and thus believes a communication should come from external somewhere, with intelligible words. But in truth there is literally no separation between you and the loved one. The loved one lives inside your heart so to speak. You can always reach the loved one instantly through your heart, nonverbally, bypassing your analytical mind.
We are simply too accustomed to communicate with words and have not been taught that we can communicate using our heart, nonverbally, and that it is a valid communication method.

Put your mind aside and allow yourself nonverbal interactions through your heart, with your feeling. Try not to decipher the message with your mind. Just feel the interactions.

Open and feel your heart, feel your love that is there, and communicate through your heart.
Heart is a window to other dimensions.
