In Vedic Astrology, Rahu is considered to be a shadowy planet that can have both positive and negative influences on an individual's life, depending on its placement in the horoscope. When Rahu is placed in the eighth house of a horoscope for Aquarius lagna, it can create significant changes and transformations in an individual's life.
The eighth house in Vedic astrology is known as the house of transformation, sudden changes, and unexpected gains or losses. It also relates to obstacles or hurdles that one may face while pursuing one's goals. Additionally, it governs inheritance, occult sciences, and mysteries of life. Rahu placed in this house can intensify all these aspects.

Moreover, when Rahu is placed here, it can aspect several other houses such as 10th (Career), 2nd (Wealth), and 5th (Children).

However, they will usually find ways out of difficult situations through unexpected means such as windfalls from ancestral property or lotteries.
Individuals with Rahu situated here are likely to be ambitious with big dreams but may struggle to achieve them due to unforeseen circumstances which disrupt their plans temporarily. They'll need strong mental resilience during times like these as their progress will be slower than others. This combination also creates somewhat of an "extremist" attitude where individuals going after their goals and ambitions, regardless of the consequences.
