Ancient sanskrit texts reveal
yaṁ yaṁ vāpi smaran bhāvaṁ
tyajaty ante kalevaram
taṁ tam evaiti kaunteya
sadā tad-bhāva-bhāvitaḥ

that whatever state of being one remember at the time of death, that state he will attain in the next life. The understanding is that whatever you do in this life will determine what you remember at the time of death. That is why many ancient cultures, like the Egyptians for example, seemed obsessed with death, because they understood that if they want to attain a particular destination in the next life, that they have to live in a certain way now and observe certain behavior.

Regarding the next destination, it is also stated
jātasya hi dhruvo mṛtyur
dhruvaṁ janma mṛtasya ca

that "One who has taken his birth is sure to die, and after death one is sure to take birth again".

this is called samsar. the cycle of birth and death, in many traditions, including Buddhism, Hinduism, Vaishavism and a number of others. The same them comes up everywhere.

The cycle can be stopped by spiritual process, but that's a bit off topic.

The point is that there are a number of destinations that you can attain, depending on your consciousness at the time of death.
