Maṅgala is far from the best planet for Tulā Rāśi ruling the opposite sign of Meṣa from there. It is opposed to the social and decorum-ruled domain of Tulā. Maṅgala is a rough and ready planet and with Śani it enters into battle there.
It receives the Rāśi Dṛṣṭi or the sign aspect of Gurū and Ketu from Vṛṣabha Rāśi, another sign ruled by Śukra/ Venus and the aspect of Gurū is a great positive for this combination which is happening here.
Maṅgala and Śani can give a warrior Yoga of fearlessness to be found in the horoscopes of army generals and the like. It gives an inflexible will and great rigidity in action. If such attributes are required by natives in any area of life to be gauged from the relevant parts of the horoscope, then this is the time during which to push forth and try and attain those objectives.
Gocara ultimately acts as the postman or the delivery boy and if the Yogas are there to be triggered and the time is right, some people may actually benefit otherwise this is a malefic association in the sign of personal relationships and marriage.
Married couples do not need to be like warriros after all, and nobody needs inflexity of will in a market place.
