Astrology is a combination of Pancha Skandhas i.e., Siddhanta, Samhita, Hora, Prasna and the Sakuna. Out of the five skandhas the “Sakuna skandha (omens) has a special significance from the vedic time. This sakuna skandha indicates benefic and malefic events which are categorized in six parts. They are :
1. Relating to grahas and upgrahas.
2. Temporary climatic conditions like air, from opposite direction, black clouds, red soil etc. before traveling or before starting new works etc.,
3. Relating to animals and birds.
4. Shivering of body, limbs and other parts.
5. Dreams
6. Animals, birds and human beings come in front while leaving house.
Except sakuna the knowledge of science is essential to understand and know its utility to comment on the remaining part of astrology. The knowledge of sakuna is spread allover the masses and the importance of it as a future indicator shows its relation to astrology. Hence it. is treated as Pancham Skandha the 5th part. The jyotisha shastra is prominent and primitive of all sciences. In samhita sakuna is one of the parts. The results of sakunas are briefly defined in panchangas also.
