Ex pg-geologists is known as Bhu gharva sastri भू -गर्भ शास्त्री.In some other term degree is awarded to pupils after years of higher education in the Sanskrit language (at institutions such as Sampurnanand Sanskrit University or Rashtriya Sanskrit Sansthan in India).The length of training required for a Shastri degree is usually seven years following the completion of secondary school, although students may continue training for an additional two years to obtain an Acharya degree.
This degree also enables pupils to become accredited Hindu Priests and Religious Teachers.
Still the issue of a certificate as an Acharya or Shastri degree in Astrology is not valid.
[4] Shastri also exists as a surname through patriarchal inheritance, and so people with the name may not necessarily have undergone its associated training.
Examples are the descendants of the Tamil Lutheran poet Vedanayagam Sastriar (1774-1864).
