Rahu
and Ketu (Lunar nodes) are going to station at 23 and 22 degrees in
Libra and Aries from Middle of March 2013 to third week of June 2013.
This would mean stress in various areas for those who have weak planets
in odd signs and/or have rising degree of their ascendant between 17 and
27 degrees. Closer the degree to 22 degrees, more the stress.
