Ithasala yoga of year
Tajaka · Year
Ithasala yoga (from Persian/Arabic ittisal, "junction" or "application") is the fundamental predictive yoga of the Tajaka annual astrology system. It occurs when two planets in the Varshaphala chart are in an applying aspect — that is, the faster planet has not yet reached the exact aspect degree with the slower one — signaling that the conjunction of their themes will come to fruition during the year.
What it is
Tajaka astrology employs a unique aspect theory that distinguishes sharply between applying aspects (ithasala) and separating aspects (musaripha). This distinction — borrowed from Arabic/Hellenistic astrological theory — is the most important evaluative criterion for whether a yoga in the annual chart will actually produce its promised results.
An Ithasala yoga forms when: (1) two planets are in one of the five Tajaka aspects (conjunction 0°, sextile 60°, square 90°, trine 120°, or opposition 180°); (2) the faster planet is within an orb of influence of the slower planet but has not yet reached exact aspect; (3) both planets are capable of producing results (not combust, not debilitated beyond recovery, not in dusthana houses without mitigation). When these conditions are met, the yoga is said to be "applying" and its promise is active for the year.
Classical Tajaka texts (Neelakantha Tajaka Neelakanthi, B.V. Raman's Varshaphala) classify Ithasala into three sub-types based on planetary speed and proximity: Poorna Ithasala (complete application, both planets are in each other's orbs and the aspect is imminent), Madhya Ithasala (middle-strength application), and Kamboola (a third planet mediates the application, amplifying the yoga).
How it is calculated
To identify Ithasala in a Varshaphala chart:
- Calculate each planet's speed for the day of the solar return (use planetary speed tables or modern software).
- For each pair of planets in aspect (within the Tajaka orbs — typically 7° for most aspects), determine which planet is faster.
- If the faster planet has NOT yet reached exact aspect with the slower planet (i.e., the aspect is applying), Ithasala yoga exists.
- If the faster planet has ALREADY passed exact aspect (separating), Ithasala is absent — this is Musaripha yoga, which indicates a promise already made but now passing away.
The strength of the Ithasala depends on the orb: within 1° of exact is considered the most potent; 1–4° is active; 4–7° is weak but present.
What it reveals
Ithasala reveals which specific planetary themes and life domains are poised to come to fruition during the year ahead. Each Ithasala yoga promises the convergence of two planets' significations — the houses they rule, the planets involved, and the nature of the aspect (harmonious trine/sextile or tense square/opposition) all shape the predicted event's quality.
For example, an Ithasala between the Varsha Lagna lord and the 10th-house lord in trine suggests a year in which career and personal vitality converge positively — advancement, recognition, or a new professional beginning. An Ithasala between Saturn and the 7th lord in square may indicate a year of relationship challenge or delay requiring persistent effort.
Ithasala yoga is generally considered the single most important yoga to check in any Varshaphala reading — a chart without any Ithasala yoga is considered "promise-poor" for the year, while multiple strong Ithasalas indicate a rich, event-filled period.
Frequently asked questions
What is the difference between Ithasala and Musaripha?
Ithasala (applying aspect) and Musaripha (separating aspect) are opposites in Tajaka theory. Ithasala means the faster planet is still approaching the exact aspect — the planetary promise is incoming and will manifest during the year. Musaripha means the faster planet has already passed exact — the promise was active in the past but is now waning. A Musaripha yoga can still carry some residual effect but its primary window has passed. Only Ithasala creates active, forward-looking promises for the year ahead.
What is Kamboola yoga and how does it relate to Ithasala?
Kamboola is a modified form of Ithasala yoga where a third planet facilitates or strengthens the applying aspect between two planets. If the two planets forming an Ithasala are separated by more than a standard orb but a third planet mediates between them — either by being in aspect to both or by carrying the application from one to the other — this mediated application is called Kamboola. Kamboola is generally considered as effective as a direct Ithasala, and in some traditions even more powerful because of the additional planetary energy it introduces.
Can Ithasala yoga occur in the natal chart as well as the annual chart?
Technically, the applying/separating distinction exists in all chart types, but in the Tajaka tradition, Ithasala yoga is specifically a concept of the Varshaphala annual chart. It is evaluated relative to the planets' speeds at the moment of the solar return. In the natal chart, Tajaka yoga theory is not conventionally applied — natal analysis in Vedic astrology uses Parashari yogas and aspects. Ithasala belongs firmly to the annual Tajaka framework.
