Its hard for us to think of viewing relationships that way, but we have not successfully journeyed to the void (legally speaking). The void is a very difficult state of awareness to maintain for even minutes, much less go there frequently. The aim of this type of meditation, is to progressively approach a place where they can maintain this void-ness for increasingly longer periods of time. Buddha is venerated for two primary reasons:
he perceived the incompleteness of the various stages of enlightenment - from India and the aesthetic practice, thru the Himalyas, to Tibet, and its religion of Bon. He perceived that true Nirvana was rare and momentary. And he perceived the state beyond Nirvana - The Void, the one really true reality, composed of an absence of all things we see, know or perceive. This is refered to as the OneTrue Space, Where no form holds, and all that is perceivable is the infinite white concious, The One. The place of origin. The one thing that is real and true, and never alters form, no matter what your personal religion beleives, the one unchanging factor to exist. eternal. bliss and pure awareness in tandem, generated by love for all beings, and your desire to have them see the one true place as well.
To Acheive by due diligence., meaning, he understood what he was, what he was capable of, and what he was not capable of, and progressively practice, to exercise, if you will, to make himself fit to have the energy and focus to work to this state of voidness. To make it short, one day he, i guess, was prepared. At any rate, he (having learned how to stay alive in the flesh for months and years on water and breath.) sat down under The Bodhi Tree, and took a vow that he would not leave this place until he died or acheived enlightement - refered to as "Vanquishing the 10,000 Worlds" - leaving behind the form of flesh and mind, and keep moving, until there was nothing but nothing.
After acheiving this state - the state called Buddha, he was from then on, a living in the flesh, person who perceived from the Void of Purity, yet was able to talk to you here, and communicate to the world. To give teachings, - sutras- guides in different formats, for techniques to be used to approach this state of Buddha. The point of Buddhas teachings was to emphasize that each incarnate being - insect, critter, human, had the absolute right to also approach, to progress thru the 10,000 worlds, and that they could, with due diligence, also be of Buddha. Indeed, His Holiness Dalai Lama 14, maintains that each of us are - now - buddhas. The problem is we forget and do not remember. The plan, i guess it could be said, is that each being that enters the void - stays there, or comes home here, to aid and assist others to enter the void. Eternal Clarity does not die. the body does. Enter Eternal Clarity, then you don't notice the changing from body to purified spirit.
so back to relationships, so you can see that we, as feeling and sensual and indulgent humans, seldom find the stength to desire that kind of conciousness, so we cannot, at this stage, make decisions from that space. but we can practice.
His Holiness The Dalai Lama, wrote a book as a man, a monk in the modern world. he wanted one teaching for acheiving this state to be accessible to anyone that read it, irrespective if they were buddhist.
As a human man his name is Tenzin Gyatcho (sp.) and his book is: "The Opening Of The Wisdom Eye"
