There could be many reasons why people don't think more about heaven. Here are a few possible factors:
Daily distractions: People are often busy with the demands of daily life, such as work, family, and other responsibilities, which can leave little time or mental energy for contemplating the afterlife.
Lack of understanding or interest: Some individuals may not have a strong belief in an afterlife or may not be interested in exploring the topic in depth.
Fear or uncertainty: The concept of an afterlife can be daunting or even frightening for some individuals, who may prefer to focus on the present rather than the unknown.
Materialism: In a society that places a high value on material possessions and success, people may prioritize earthly pursuits over spiritual ones.
Skepticism: Some individuals may be skeptical of the idea of heaven or may have questions or doubts about its existence, which can make it challenging to focus on the topic.
Overall, there are many distractions and competing priorities that can prevent individuals from thinking more about heaven. However, for those who are interested in exploring the topic, there are many resources available, including religious texts, philosophical discussions, and personal reflection.
Cultural Influences: Cultural shifts and changes in societal attitudes can also impact how much people think about concepts like heaven. Modern societies might place more emphasis on secular concerns and scientific understanding.
Spiritual Diversity: Even among those who believe in heaven, the specific nature of that belief can vary. Some may think about heaven regularly, while others might have different interpretations or varying levels of engagement with the concept.
