According to sage agasthiar people have to get blessings of god, elders, yogis, gurus, acharyas before starting doing any good thing or parigaram.
For sate sati (71/2 saturn), astama sani, saturn dasha ketu bhukthi, ketu dasha saturn bhukthi one has to read first sargam in sundara kandam.
For marriage, job, separated couples sage agasthiar prescribes sargam 5,6 and 7.
Sage agasthiar had prescribed Sargam 1 to 9 in sundara kandam to get rid of ragu, ketu and Saturn doshas permanently.
