Importance of eighth house in Indian astrology

The eighth house of horoscope is referred to as the house of sex.This house delves into relationship-interactions with another and how certain aspects of those interactions can take on a more communal nature. It speaks to what our relationships will bring us and how we can get the most out of them.
Returning to this house’s emphasis on sex, it’s important to note that the French refer to an orgasm ‘le petit mort’ or ‘the little death’. When we reach that exalted state of communication, we live a little of ourselves behind-die a small dealth.One can also choose to view this as growth, a new beginning, the rebirth of the soul or a gain for the partnership. The eighth house of horoscope is an equal opportunity house, placing sex, death and rebirth on the same level playing field and acknowledging the viability and importance of all three. We will all experience death and rebirth as part of our lives; failed relationships leading to new ones, career changes, a new hairstyle. We are generated and reborn with each new phase and should welcome them.
Shared resources also fall within the eighth house: inheritance, alimony, taxes, insurance, and support from another. Financial supports as well as spiritual, emotional and physical support are addressed by this house. While our relationships share many of the aforementioned things, they also have their own dynamics and grow from within.
In keeping with the transforming nature of this house, rituals are highlighted .Every group has its own way of peering in and looking deep into the soul and the past, if only to get a sense of what we truly are. Our legacies are key to this house: how we conduct ourselves now, and how that will play out for all time.

In essence, the eighth house signifies all things hidden; the rectum, serious diseases, concealed wealth, lotteries, knowledge of the hidden laws of nature, gains or losses from market fluctuations, psychological afflictions or mental sufferings which would be unseen to others and even death.-which is in fact the hidden existence of the individual after the close of life. Thus the eighth house of horoscope symbolizes the powers in nature embodied as the Kundilini Shakti.
The eighth house is ruled by the sign Scorpio and the planet Mars.
