According to Osho, blissfulness is primary; gratitude flows from it. First, through meditation your consciousness flowers into a living silence, peace, and ecstatic dance—this direct encounter with existence (not a personal God) births spontaneous, unaddressed thankfulness. True prayer is prayerfulness: a natural overflow of bliss, free of desire or bargaining, revering the godliness shimmering in life itself.
Find inner joy through meditation, and then real thankfulness naturally appears without asking for anything or addressing a god.
