Buddha taught us 2,500 years ago that life is suffering. This world is called Samsara (Ocean of Suffering). Our body fails us every now and then. Our friends and relatives fail us often. Our objects of desire are ephemeral. Our desires themselves are ephemeral.
Why would we not have a sincere wish to transcend this samsara? What is the way out?
The surest way out is Detachment. But detachment is not easy. How do we achieve detachment? Ketu (one of the nodes of Moon) is the planet of detachment in Vedic astrology. Wherever Ketu is placed in our chart is the area which we have mastered in the past life. That is the area which can help us achieve an attitude of detachment. For example, if we have Ketu in the 6th House, then serving others is the way out for us. If Ketu is in the 9th House, then higher knowledge and wisdom can be our best ally.
