Alexey Borealis (also publishing as Mark Rusborn) brings an unusual background to astrology. Unlike many practitioners who come from purely esoteric traditions, Borealis began in the hard sciences:

Borealis also holds a Diploma in psychology with specialization in Erickson's hypnosis and completed training at the Process Work Institute in Zurich. However, he notes that he has discontinued his psychological practice, considering it incompatible with predictive astrology work.

This unusual combination — hard science, traditional astrology, and psychological training — creates the foundation for the Morinus approach.

The Morinus school explicitly positions itself against what it calls "vague formulations or personality descriptions." Instead, they promise "specific, unambiguous predictions" based on "rigorous mathematical calculations, verifiable methods and logical synthesis of data."

"Our approach is not about divination, but about rigorous mathematical calculations, verifiable methods and logical synthesis of data. We teach astrological thinking—the ability to analyze, compare facts and draw evidence-based conclusions."

This scientific framing is reinforced by several key principles:

• No esotericism — only verifiable methods
• Statistical research — testing astrological laws on data arrays
• Renaissance traditions — astrology as an academic discipline, not entertainment
• Morinus over Lilly — preferring the mathematical Jean-Baptiste Morin to the more accessible William Lilly

The school has received official recognition from APAI (Association of Professional Astrologers International), and its courses rank in the Top 10 on Udemy, with a 9.7/10 rating from CourseMarks based on 18 criteria.

The "Advanced Training for Horary Astrologers: How to Achieve Day-Level Accuracy" is designed for practitioners who already feel confident with simple horaries but struggle with complex, atypical questions. You can explore the official course page here for the most current details.

Curriculum Highlights

One of the most striking claims in the Morinus course materials is this:

"Most schools rely on the works of William Lilly, which contain many inaccuracies and inconsistencies. Our methods includes the techniques of Jean-Baptiste Morin (Morinus), a 17th-century professor of mathematics and astrologer. This changes everything—orb values, significations, celestial conditions, approach to aspects and receptions."

This is a significant claim. William Lilly's Christian Astrology (1647) is widely considered the foundational text of horary astrology. To suggest that Lilly contains "many inaccuracies" is to challenge the very foundation of most horary practice.

Morinus (1583-1656) was indeed a mathematician and astrologer to Cardinal Richelieu. His approach was more systematic and mathematical than Lilly's, which some find more rigorous and others find overly complex.

The course is offered in three formats. For complete and up-to-date pricing, always refer to the official enrollment page.

*Tax may be added depending on your country. The Full Diploma Course requires passing the horary test and a second part on natal astrology with 76%+ for APAI-recognized certification.

• Exceptional Credentials: Borealis's background in physics and traditional astrology is genuinely unusual and lends credibility to his claims of a "scientific" approach.
• Structured Curriculum: The course is meticulously organized into 100 discrete lessons, making it easy to navigate and review specific topics.
• Real Predictions: Students make over 30 real predictions, comparing their results with actual outcomes—a practical approach rare in astrological education.
• Proprietary Software: The included software handles routine calculations, allowing students to focus on interpretation rather than mathematics.
• Professional Recognition: APAI recognition and strong ratings from CourseMarks and Udemy suggest quality that's been vetted by third parties.

• The Lilly Question: If you've already invested heavily in learning Lilly's methods, the Morinus approach may require significant unlearning. The course explicitly positions itself against "most schools" that follow Lilly.
• Price Point: At over $1,400 for the VIP package, this represents a significant investment. The demo option at $10 is a smart way to test compatibility before committing.
• Self-Paced Format: While flexibility is valuable, some students struggle with pre-recorded courses that lack live interaction. The "no feedback" in lower tiers may be challenging for beginners to advanced work.
• Scientific Claims: The course promises "verifiable methods" and "statistical validation," but astrology remains a contested field. Students should evaluate these claims critically.
• Language: While the course is in English, Borealis's background and the availability of Russian-language options suggest some materials may reflect non-Western pedagogical approaches that could feel different to some students.

The Morinus Advanced Training is not a course—it's a system. Alexey Borealis has built something genuinely distinctive: a bridge between Renaissance astrological precision and modern scientific expectations.

The credentials are impressive, the curriculum is thorough, and the results (based on student testimonials and third-party ratings) appear legitimate. The proprietary software and 30+ real predictions offer practical value that many astrological courses lack.

However, the investment is substantial—both financially and in terms of unlearning potentially conflicting approaches. The $10 demo is a wise starting point for anyone considering the full course. You can explore all options directly on the Morinus course page.

As with any advanced training, the real question isn't whether the course is "good"—it's whether it's good for you and your specific astrological journey.
