Muhurta is an important pillar of Astrology. Muhurta has been dealt with extensively in Muhurta Chintamani. Brihat Sambila and in other classics. Muhurta is selected to ensure smooth unhindered completion of some important tasks. In transit, planets go on producing numerous planetary combinations. (Some of these are auspicious while some others are inauspicious.

Working out the auspicious muhurtas and utilising them for the appropriate activity helps in smooth completion of the activity. Identification of a suitable moment for the commencement of any activity is known as the determination of Muhurta. Muhurta cannot change the circumstances but it can change their direction. Commencing an activity in a good muhurta can improve one's destiny. The wise have mentioned different muhurtas for different types of activities. There are 30 muhurtas in one day and night. There are 15 day muhurtas and 15 night muhurtas. They are based on the 27 nakshatras. Ardra and Rohini nakshatras are in the day and also in the night. In the day time Ardra is called Gireesh and during the night it is called Shiva or Rudra, Rohini is called Vidhata during the day and Dhatra Swami during the night. Dividing the Dinman by 15 gives the duration of one muhurta. If the Dinman is of 30 ghatis and 15 palas, then dividing this by 15 gives the duration of one muhurta as 2 ghatis and 1 pala. One ghati is equal to 24 minutes and one pala is equal to 24 seconds. This gives the duration of one muhurta as 48 minutes and 24 seconds in this case. However duration of muhurta varies according to the duration of dinman. Atharvaveda gives guidelines for commencing an activity in an auspicious muhurta.

The puranas describe 15 'Sarva Sidhiprada' muhurtas. Of these 8 are especially auspicious. The first position belongs to Abhijeet muhurta. This is also known as the Vijay muhurta. 'Abhijeet muhurta' is available every day from 11.45 AM to 12.30PM. According to Naiad purana', Abhijeet muhurta starts at 11.36 AM and ends at 12.24 PM. Activity started in this muhurta normally succeeds and no other considerations are required for this muhurta.

Lagna Shuddhi

Benefic planets should be placed in the first, second, third, fifth, seventh, ninth, tenth and the eleventh houses of the muhurta lagna. Malefics should be placed in the third, sixth or the eleventh house. Fourth and the eighth house should be unoccupied by any planet.

Vama Ravi Consideration
Ravi vichar is done for the griha pravesh lagna.
  • If Sun is placed in any house between the fourth and the eighth house then it is vama for entering into to a house with the door in the East. This would be auspicious
  • If Sun is placed between the fifth and the ninth house then it is vama for entering a house with a door in the South
  • If Sun is placed between the second and the sixth house then it is vama for entering a house with a door in the West
  • If Sun is placed between the eleventh and the third house then it is vama for entering a house with a door in the North

These are considered favourable.

Example : In the given horoscope of Leo lagna, Sun is placed in the twelfth house, which is vama and auspicious for entering into a house with a door in the North. The door of the concerned house is in the West, so the muhurta is not suitable for grih pravesh.
