What is the significance of Venus in Leo, Mars in Cancer, both in 8th House, Cancer ruling the house?

And what does having Jupiter at "critical" 26 degrees mean?

So much to learn...
Can someone Enlighten me please?

a critical degree is a degree in the horoscope that is felt to have significance. The concept of the critical degree is based on Hindu technique of Lunar Mansions, which subdivides the horoscope into 13 degree segments, which is the Moon's average daily motion. When a planet or point falls on a critical degree it is often believed to be strengthened because it is on the cusp of the 13 degree house sub-division. The critical degrees are as follows:-

   * Aries - 0, 13, 26
   * Taurus - 9, 21
   * Gemini - 4, 17
   * Cancer - 0, 13, 26
   * Leo - 9, 21
   * Virgo - 4, 17
   * Libra - 0, 13, 26
   * Scorpio - 9, 21
   * Sagittarius - 4, 17
   * Capricorn - 0,13,26
   * Aquarius - 9, 21
   * Pisces - 4, 17
