Bliss is never experienced when we are high on something or even on someone! Not the kind of bliss that is stimulated in any way. This is the natural bliss of the soul, of the self, when we are completely free internally. this is freedom from attachment to everything around us including matter, material things, memories, ambitions etc. But it's only possible when we see and realize that our attachments are not 'in reality' out there! Our attachments are created within our own consciousness. It's not the actual objects or persons that we attempt to attach to.
Detachment is not losing or living without all these things or people etc., it's not an avoidance of others or an uncaring attitude. Detachment doesn't diminish our capacity to 'be loving'. Detachment means we no longer 'create' the perception and feeling of being burdened by the other, of being dependent on others or being beholden to others. Like everything else people come and go, they are all there in the dynamic of daily life, part of the fabric of our life, detachment means we cease to make them our source of happiness in life.
The inner state of freedom that gives rise to the feeling of bliss is already there but it's been suppressed and buried. It has been lost to our day-to-day awareness. Almost all addiction is the result of an attempt to resurrect, release and taste the bliss, the purest form human happiness. For centuries meditation and contemplation have been practiced as the natural ways to restore this natural and original state of inner freedom. Attachment is essentially what makes us take life too seriously simply because we make ourselves slaves to the objects of our attachments. In such moments we don't have possessions, it's as if our possessions have us. Liberation from attachment happens when we not only stop attempting to possess but realize its impossible to possess! This then frees us to 'play' at life, to be 'playful' in life, not in a childish way, but in a way that allows our joy and our bliss to shape the energies that we give to others.
This kind of bliss is the highest happiness. It seems impossible in the daily routines of our material lives with all its apparent ups and downs, joys and sorrow, victories and defeats, losses and gains. And yet, even then, we all have our moments. We all know those moments when, if only for a few moments, we forgot about our self and everything that we had learned to grasp, we forgot our past and we even suspended our hopes and enthusiasms for the future. And in such moments there is a deep and profound feeling of freedom and we feel the bliss of being a completely free spirit. Our heart sings and our soul dances like young swallows on a warm summers evening singing with delight as they learn and taste the bliss of free flight.
