How can the understanding of death be integrated into Tantra?

According to Osho, Tantra integrates death by recognizing life and death as one continuum: begin with total involvement in life but inquire so deeply that you also know death, and through that awareness transcend both into the deathless. Buddha starts from death, Tantra from life—the source is the same. Death-awareness dissolves false “life,” guiding Tantra toward what is beyond birth and death.
