The fruit of attachment is tears. This applies to all types of attachments.
Relationships
Don’t aim for making every one happy. You and your cautiousness should be in total control of your decisions. Don’t take decisions to make your spouse or parents, or children happy. Listen to them and their expectations from you; but ultimately, let your cautiousness decide. Remember most people are selfish and that includes your family members including yourself.
Learn to live alone because most relations break during tough times. Once you have learned to live alone, you will never miss the family gatherings or parties. You will soon start enjoying your company more than you had ever enjoyed.
When you leave all relations behind, your desires decrease. Corruption decreases, greed decreases, and you become a better person. And this will have a huge impact over the kind of karmas you do in your life.
A person in relationships tries to meet desires of himself, parents, and family. The resulting actions that arise from desires of family members often result in too much stress, hard work, and sometimes even corruption or criminal activities.
Love
Never will of pain for others as it will bring pain to you. Never will of making other people envy or jealous of your lifestyle as it will make you more jealous of people who are more wealthier than you. What you give, you get in return.
Which means the purpose of your life should be to spread love as that’s the only way you can bring positivity in your life and to the world.
Don’t confuse love with relationship. Love is a state of your being, not a relationship. Love is a moment-to-moment process.
Love may not return from the same person, but it will return for sure. And if it does not return, then there is only one possibility. Think again, had you really given pure love? Or just pretended to give love.
