Jyotishi Sri AMR practices in Chennai, India. He is a 87-yr old veteran Jyotishi who holds the chair position for a jyotish/spiritual magazine as well as gives free readings and guidance for needy people at Kumudam.com Jyotish section. I've read many of his suggestions for remedies and I've been greatly impressed by their practicality, which I thought I would share here:
i) He greatly advices on lighting a ghee lamp on the day signifying the afflicted planet at a nearby temple for 48-consequetive weeks, sometimes if the affliction is very severe, for as much as an year or 2 years.
ii) In one case of difficult to diagnose and treat illness, he adviced on reciting Dhanvantari Mantra over plain water 108 times every day (making it carry the vibrations of the mantra-japa) and consuming this for a period of 2 years.
iii) If there is no temple nearby or they don't allow lamps to be lit at the temple (like the ones in USA), he advices on lighting an extra lamp at home itself at the puja on the day signifying the afflicted planet. He calls this 'Vilakku poduthal' in Tamil.
iv) He advices on keeping a picture of 'Embaar' (Sri Govinda bhatta, the birth name for Sri Embaar, was the maternal cousin of Sri Ramanuja) on certain occassions on an elevated platform or table in the middle of the room, circumambulating around it and offering milk with added 'Kalkandu' as prasad/naivedyam and consuming it for 48 consequetive days. I've seen him advice similar parihara for various doshas including loss of sight to be done to several saints such as Srimad Ramanuja - an easy parihara.
v) For educational issues, he advices reciting slokas for Sri Hayagriva in the same way as stated in point 4 for 48-days and consuming his prasad.
vi) For all childless couples, he has by-default adviced on reciting Sri Santhana Gopalakrishna sloka which he personally delivers via post (the picture and the sloka) to the needy.
vii) For debts (and court cases), by default, he advices on reciting Runa Vimochana Stotra to Sri Lakshmi Narasimhar or there is an equal Shaivite stotra for the Shaivas, for a 'mandala' or more.
viii) For some cases such as lost child, etc, he advices on people taking a pilgrimage to the Navabrindavana of 9 great Madhwa saints in Karnataka followed by a suitable parihara.
Many people have written back to him praising him how the pariharas have improved their lives and remedied the symptoms - the speechless have started to speak, the dull student became bright, the childless got a child, the court case ended in success, and so forth..
Just thought of adding this note here, because the pariharas are so very simple to do, and the rewards are great...
