Buddhism and Hinduism share the belief in reincarnation, where the soul is reborn based on past actions (karma).

The goal in both is to escape the cycle of rebirth and attain liberation (nirvana or moksha).

the purpose of life is to achieve nirvana, a state of freedom from suffering and rebirth.

purpose of life is to experience to maximum
no matter whether you're born poor or rich  ugly or good looking
everybody "image" will decay
thats why buddhism and Taoism focuses on the soul and letting go

Wealth and Suffering:

The idea that those born into wealth do not suffer, while those born into poverty inevitably do, is a common misconception.
While it's true that material wealth can alleviate some forms of suffering, it does not remove the deeper forms of dissatisfaction that exist within us—such as the
fear of loss, loneliness, or existential anxiety.

Similarly, poverty does create hardships, but it also offers opportunities for resilience, growth, and a deeper understanding of life's impermanence.

In both cases, suffering comes from our attachment to what we have or do not have.
Wealth may ease physical pain but cannot guarantee peace of mind or spiritual fulfillment.

We are eternal beings who are always living. Coming to this material world & going through sufferings in various bodies is due to our own free will.

You are always free to renounce the attachment to the material body & hence the material existence & go back to your constituitional position as a blissful soul.

The souls (jivatma) exist because the Supersoul (Paramatma) exists,  the souls being parts & parcels of the ever existing Supersoul. Our constituitional position is to exist as eternal servitors of the Supersoul. But we may renounce the path of dedication & choose the path of exploitation of material nature, or vice versa, because of our free will.

There is. We exist as servants of God in His eternal kingdom & servants of nature in this material kingdom. In other words, we were created to exist & serve (or exploit).
