Kruchha vrat - equivalents - as per Parasara smruthi

 Following has been taken from Tamil translation of Parasara smruthi by Desikachariyar

Chating gayathri japram for 10,000 times

200 pranayamam

Takea dip in sacred water, chant tarpana japams, come out and dip again - repeating this 12 times

Going for theertha yatra that is 2 yojana distant (1 yojana = about 8 miles = about 12.8 km)

These are equivalent to one Krucha vrat
