Saturn in the Lagna Aspects the 3rd, 7th, and 10th

Saturn in the ascendant aspects the 3rd, the 7th, and the 10th, not the 2nd or the 11th. Its third aspect falls on the 3rd house, its seventh on the 7th, and its tenth on the 10th. Wealth is judged from the 2nd and the 11th and from their lords. A planet that does not touch those houses is not a wealth planet merely because it sits in the 1st. What Saturn in the lagna does give is a serious, enduring temperament, often a slow start, and a strong hand on career because the 10th is under its special aspect. People feel the career and call it wealth. The 11th lord may be a different graha entirely.

Shasha yoga forms when Saturn is in a kendra in its own signs or exaltation: Capricorn, Aquarius, or Libra. The lagna is a kendra, so Saturn in the ascendant forms Shasha only when the ascendant itself is one of those three signs. Saturn in a Cancer lagna is in an enemy sign in the 1st, not Shasha, and not a wealth blessing. Saturn in Libra lagna is exalted in the 1st and does form Shasha, with Saturn also ruling the 4th and 5th as yogakaraka. That chart can support resources because the whole lagna is strong, and you should still read Mercury or whoever rules the 2nd. The yoga is stature and stamina. Dhana yoga is a separate joining of the 2nd and 11th lords.

Saturn's digbala is the 7th house. The lagna is not Saturn's strongest direction, so the popular claim has the place slightly wrong even before wealth enters. Saturn in the 7th in Libra, Capricorn, or Aquarius has both Shasha and digbala. Saturn in the 1st has Shasha only in those signs, without digbala. Neither placement deposits cash in the 2nd. During Saturn's 19-year mahadasha, a lagna Saturn reorganizes identity and the 10th. Income rises if the 11th lord also runs or is joined to Saturn by lordship. If Saturn rules the 11th, as it can for a Pisces lagna where Aquarius is the 12th and Capricorn is the 11th, then Saturn in the 1st is the gains lord in the body, which is a real money contact.
