All attachments lead to more attachments and passionate entanglement. When these strong passions are not fulfilled, then it leads to anger and more obsession and then it leads to even more attachment and this becomes a negative spiral that easily gets out of control and makes the person lose their peace of mind.
Peace of mind is absolutely essential for each one of us. It is needed for us to even lead a normal life. Even if one wants to enjoy their lunch or sleep; we need to have a peaceful mind. If our mind is always turbulent, we will not be able to perform life’s most simple tasks and we definitely cannot feel joy without first there being peace.
So, when we get entangled in attachments and this in turn gets us more and more entangled in the situation, this initially turns to frustration, but this frustration soon leads to anger. When we are angry, it is even more difficult for us to see reason and re-attain our sense of mental balance. Because of this, it leads to more and more to frustration and anger to the point to one’s complete destruction.
There are many instances in history that indicate how strong infatuations, attachments and other such strong acts of passion- has led to anger and ultimately fall of great Men and Women (of apparent wisdom) along with their vast Kingdoms!
The cycle of attachment unless broken, always leads to more attachment and finally to one's destruction. It keeps us caught in this cycle of "birth and death", lifetime after lifetime!
This quote by Lord Krishna, from The Bhagavad Gita beautifully explains this important lesson:
"One develops attachment to sense objects by thinking about sense objects. Desire for sense objects comes from attachment to sense objects, and anger comes from unfulfilled desires.
Delusion or wild idea arises from anger. The mind is bewildered by delusion. Reasoning is destroyed when the mind is bewildered. One falls down from the right path when reasoning is destroyed.”
- From The Bhagavad Gita: Chapter 2 and Verses: 62- 63
