Wisdom from the example of Lord Buddha.

Ten hindrances to enlightenment:

1. The belief in a permanent personality, ego (Pali: sakkāya-diṭṭhi)
2. Doubt, extreme skepticism (vicikicchā)
3. Attachment to rites, rituals, and ceremonies (sīlabbata-parāmāso)
4. Attachment to sense desires (kāmacchando)
5. Ill-will, anger (vyāpādo or byāpādo)
6. Craving for existence in the Form world [heavenly realms] (rūparāgo)
7. Craving for existence in the Formless world [heavenly realms] (arūparāgo)
8. Conceit (māna)
9. Restlessness (uddhacca)
10. Ignorance (avijjā)

(from Anguttara Nikaya 10.13)

Renunciation, listed above does not necessarily mean giving up your possessions and becoming a monk or nun. Renunciation can simply mean being content with what you have and maintaining a simple life and lifestyle. It can mean “counting your blessings” or doing something simple to put your mind at ease to allow you to pursue spiritual quests. It can also mean making some small sacrifices, such as choosing your vacation time from work to go to a vipassana retreat, instead of a cruise.

The Buddha spent many past lives as an ascetic monastic perfecting each of the ten perfections. He could not be re-born in his final life as the Buddha until all ten perfections were fully developed. Enlightenment is not something so simple as just sitting one day and all of a sudden feeling at “one with nature” and very “awake.” There is a common danger in many Western countries where some practitioners and teachers say that they are enlightened when they have one momentary glimpse of jhanic pleasure in their meditation. They are mistaking some pleasurable jhanic states for enlightenment. Enlightenment is attainable, but no easy task and has the prerequisite of the ten paramitas.
