Brihadyatra 8: adhyāyaḥ 8

All bipeds are under the control of quadrupeds, except the Lion; the water-dwelling signs are subservient to reptiles.

These remain under the control of the king of beasts, excluding reptiles; in the case of signs not mentioned, the subservience should be inferred from the worldly conduct of people.

Land-dwellers, water-dwellers, and reptiles accept submission after looking at the strength of their own kind.

During the day, even signs are under the control of odd signs; at night, odd signs are subservient to even ones.

In a head-rising sign, there is accomplishment of the desired task; in a rear-rising sign, failure and the rout of one's army.

For one facing the direction of travel, there is success with ease; through an ascendant contrary to the direction, there is wasted effort.

Departure by day is recommended in a sign strong by day; at night, in a sign strong by night; marching in a sign whose strength is reversed is not recommended.

When the Moon, Sun, and ascendant are situated in movable, [fixed, or double-bodied signs], departure grants increase respectively to another's land, one's own land, or both lands.

When Pisces rises, for one departing, the journey is crooked and full of troubles, and there is return without having accomplished the task.

Even in other navāṃśas in Pisces, the result is precisely this; and also in the navāṃśas of Pisces resting upon other signs.

In the eighth house of the enemy, there is destruction of the enemy; when the sixth house of the enemy rises as the ascendant, there is the slaughter of the marching one.

This is the rule of Satya; in the tradition of Vaśiṣṭha, this is not absolute.

If at the enemy's time of birth the eighth house is joined with malefic planets,

or the sixth is joined with benefics, then the good or bad result comes from both of those.

Departing when his own natal sign is joined with the ascendant, he attains destruction of enemies and gain of wealth without distress.

In the second, loss of wealth, fatigue, and misfortune [occur]; however, some declare the arrival of welfare, comfort, and prosperity.

In the third, there are servants, wealth, conveyances, allies, and victory; in the fourth, destruction of relatives and wealth, fear, and slaughter of the army.

In the fifth house, there are breach of counsel, calamity, and increase of enemies; in the sixth, acquisition of the enemy's wealth, army, splendor, and victory.

In the seventh, misfortune with paths and conveyances, hunger, affliction from excessive fatigue, imprisonment, slaughter, and defeat; in the eighth, diseases.

In the ninth, loss of wealth, illness, failure in undertakings, and fears; in the tenth, panic in the army without any purpose, and ruin.

Some say that this [tenth house] is counted as an upacaya; therefore departure in the tenth house rising is auspicious.

In the eleventh, there are gain of wealth, splendor, auspicious success, and victory; in the twelfth, treachery, danger of expenditure, and discord even if victorious.

From disease, when the natal sign rises, there is the slaughter of a son; and failure in the fifth from it.

In the seventh from the natal house, after experiencing distress, he subsequently attains happiness.

In the ninth house, there is turning back right from the road; in the tenth house, acquisition of wealth.

In the remaining asterisms, the result from the natal sign is just as it is from the ascendant house.

When the hot-rayed one is in the eastern ascendant, there is affliction from hunger and thirst, loss on the road, eye disease, and attainment of distress.

In the Moon's [ascendant], it is auspicious for divine purposes in one's own country; in Mars's, affliction from bile, serpents, weapons, and fire.

In Mercury's, there is contentment, attainment of what is desired, and fame; in Jupiter's, gain of wealth, status, honor, and destruction of enemies.

In Venus's, there is acquisition of women and jewels, and success in tasks; in Saturn's, imprisonment, disease, and humiliation by the base.

Even a benefic which does not bestow the fullness of auspiciousness at birth—its sign is not auspicious for one departing as the ascendant.

Even a malefic which brings about auspicious results for men—its sign situated in the ascendant is considered desirable.

A sign that is not subservient to both the natal and ascendant asterisms of marching men,

even if the ascendant is favorable, brings about loss of wealth and fatigue.

When the rising sign has attained friendship and subservience to both one's natal and ascendant asterisms,

even if it causes decline, there is swift arrival of victory, wealth, and honor for the marching one.

Some say: that ascendant sign in which a planet makes a fractionless point,

because that sign is undesirable for the marching one, giving fear, grief, and agitation.

With Taurus, Scorpio, and Cancer occupying the ascendant, even if favorable for men,

the sages declare departure to be inauspicious, even when combined with other signs.

[…]

The veśi-planet entering the ascendant brings attainment of fruit to one wishing to depart, even without effort;

Travel by boat is desired when a water sign is in the ascendant, or in its division (aṃśa), even when another sign rises.
