There is no satisfying the senses, not even with a shower of money. "The senses are of slight pleasure and really suffering." When a wise man has realised this, he takes no pleasure, as a disciple of the Buddhas, even in the pleasures of heaven. Instead he takes pleasure in the elimination of craving.
All of you knowing now, Tthat the Buddhas, the Teachers of the Ages, In accord with what is peculiarly appropriate, have recourse to expedient devices, Need have no more doubts or uncertainties. Your hearts shall give rise to great joy, Since you know that you yourselves Shall become Buddhas.
Through zeal, knowledge is gotten, through lack of zeal, knowledge is lost; let a man who knows this double path of gain and loss thus place himself that knowledge may grow.
Hinduism threw away Buddhism after taking its sap. The attempt of all the Southern Acharyas was to effect a reconciliation between the two. Shankaracharya's teaching shows the influence of Buddhism. His disciples perverted his teaching and carried it to such an extreme point that some of the later reformers were right in calling the Acharya's followers "crypto-buddhists".
Misunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"
In Aryans' Discipline, to build a friendship is to build wealth, To maintain a friendship is to maintain wealth and To end a friendship is to end wealth.
