Younger Siblings are found in radix by counting increments of 3 houses, starting from the 3rd house, as follows:

• your immediate younger sibling = house 3

• hat immediate younger sibling's younger sibling = house 5

• next younger one = house 7

• next younger one = house 9

• next younger one down the line = house 11, and so on

Elder Siblings are found in the radix by counting increments of 3 houses, starting from the 11th house, as follows:

• you are #1 = the first house, or lagna

• your immediate elder sibling = house 11

• hat immediate elder sibling's immediate elder sibling (i.e., two above you in birth order) = house 9

• next elder = house 7

• next = house 5, etc.

If your sibling group is large enough to have duplications - more than six children - there will be powerful similarities between the siblings who end up being represented by the same house.

• E.g., if you are the eldest of eight children, you will notice strong similarities in your relationship to your immediate younger sibling and your 7th younger, between #3 sibling in your family and #8, etc.

• Look for the relationship between the two houses in question to see the relationship between you and that sibling.

• E.g., if Saturn occupies house 11 And you have an immediate older sibling, we know that this sibling is under a lot of pressure, has major obstacles, etc. and also that sibling applies pressure on to you because Saturn sitting in 11th house will aspect the lagna - which represents you.

• Surya (Sun) radix-11 nearly always "destroys" the elder sibling. ypically Surya in 11 signifies that the native is the eldest child in his/her family.

• Unimpeded Mars *drishti* to sahaja bhava will normally guarantee the birth of younger siblings

• Check other indicators such as Saturn aspects to make sure, but usually Mars aspect to sahaja bhava is fruitful for siblings.

• However, Mars *occupying* house-3 frequently denies the birth of younger siblings

• Again, check other aspects. E.g., Moon occupying sahaja bhava Or an exalted L-3 are helpful energies which might create a good sibling despite the " karako bhavo nashto" which occurs when karaka Kuja occupies the sibling house.

Yoga for siblings:

If Sahaja's lord along with Mangala drishtis Sahaja Bhava, the native will enjoy good results due to Sahaja Bhava. Alternatively, these two grahas may be in Sahaja itself." -- BPHS Ch. 12, Shloka 2

Yoga for no siblings:

Should Sahaja's lord and Mangala be together in Randhra Bhava, destruction of co-born will result. Happiness in this respect will come to pass if Mangal or Sahaja's lord is in an angle or in a trine or in exaltation, or friendly divisions. -- BPHS Ch 14, Shloka 5-6

• In matters regarding siblings, most Jyotishi will consult the special 3rd harmonic chart called the D-3 -- i.e., "Drekkhana."
