The Law of Growth in New Thought philosophy is the principle by which thoughts take form and materialize in physical reality. Charles Haanel taught that thought is spiritual energy that grows according to this fundamental law until it manifests externally. This metaphysical principle explains how mental images, once accepted by the subconscious mind, develop through natural processes into tangible experiences and conditions.

Understanding Growth, Law of in New Thought

In Haanel's system, the principle by which thoughts take form and materialize: "Thought is spiritual energy... How does it take form? By the law of growth." Haanel teaches that every mental image, once accepted by the subconscious, grows according to this law until it manifests externally. In Troward's Edinburgh Lectures, the Law of Growth is an entire chapter, establishing that subjective mind obeys the suggestions of objective mind and that growth follows the pattern impressed upon it.

The Law of Growth, a foundational principle within New Thought, posits that all phenomena, particularly mental constructs, develop and expand over time until they reach full manifestation. This concept is deeply intertwined with the idea that thought is a creative force, and that consistent mental imagery or belief will, through an inherent process of growth, materialize in the external world. Its significance lies in providing a mechanistic explanation for how intention translates into reality, thereby empowering individuals to consciously direct their experiences. Historically, this law provides a bridge between metaphysical idealism and practical manifestation, offering a framework for understanding the dynamic interplay between the inner and outer realms.

What the Teachers Say

Charles Haanel
The Master Key System

Haanel presents the Law of Growth as the fundamental mechanism of manifestation, stating that "thought is spiritual energy" that takes form through this universal principle. He teaches that every mental image, when properly impressed upon the subconscious mind, grows automatically according to natural law until it appears in the external world. Haanel emphasizes that this growth is not miraculous but follows precise spiritual and mental laws that can be understood and applied systematically.

Thomas Troward
Edinburgh Lectures on Mental Science

Troward dedicates an entire chapter to the Law of Growth, establishing it as a cornerstone of mental science. He explains that the subjective mind obeys the suggestions of the objective mind and that growth follows whatever pattern is impressed upon it. Troward emphasizes that this law operates with mathematical precision, causing thoughts to reproduce themselves in form according to their essential nature and the mental conditions under which they are held.

Ernest Holmes
The Science of Mind

Holmes incorporates the Law of Growth into his systematic approach to mental treatment and spiritual mind treatment. He teaches that consciousness grows into form through this law, making it essential for practitioners to understand how thoughts develop from seed ideas into full manifestations. Holmes emphasizes that the law operates impersonally, growing whatever is planted in consciousness regardless of whether it serves the individual's highest good.

Growth, Law of vs. Law of Attraction

While both the Law of Growth and Law of Attraction explain how thoughts become reality, they emphasize different aspects of the manifestation process. The Law of Growth focuses on the developmental process by which thoughts mature into form, while the Law of Attraction emphasizes the magnetic principle that draws corresponding experiences.

Etymology

The term 'growth' originates from the Old English 'growan', meaning 'to sprout, increase, develop'. 'Law' derives from the Old English 'lagu', referring to a rule or principle. In the context of 'Law of Growth', these terms combine to describe an inherent, governing principle of development and expansion, particularly as applied to mental and spiritual processes within New Thought.

How to Practice This

Practitioners of New Thought apply the Law of Growth by consistently holding clear mental images and affirmations of their desired outcomes. This involves daily visualization exercises, where one vividly imagines the desired state as already achieved, and repeating positive affirmations to impress the subconscious mind. The key is sustained focus and emotional engagement with the desired thought-form, allowing it to "grow" and gather momentum until it manifests in the physical world. This conscious and persistent mental cultivation is believed to activate the law, leading to tangible results.

Connection to Manifestation

The Law of Growth serves as a foundational principle for understanding how manifestation actually occurs in the creative process. Rather than suggesting that desires instantly materialize, this law explains that thoughts must first be planted as seeds in the subconscious mind, where they grow and develop according to natural principles. Practitioners of manifestation techniques benefit from understanding that their mental images require consistent nurturing and patience, just as a gardener tends to growing plants. This perspective helps explain why some manifestations appear quickly while others require extended periods of mental cultivation before appearing in physical form.

Frequently Asked Questions

How does the Law of Growth work in New Thought?

The Law of Growth works by taking mental images accepted by the subconscious mind and developing them according to natural principles until they manifest externally. Like a seed growing into a plant, thoughts develop from their original form into corresponding physical experiences through consistent mental attention and emotional energy.

What is the difference between the Law of Growth and manifestation?

The Law of Growth is the underlying principle that explains how manifestation actually occurs, while manifestation is the end result of this process. The law describes the developmental mechanism by which thoughts mature into form, whereas manifestation refers to the final appearance of the desired condition or experience.

How long does the Law of Growth take to work?

The timeframe varies depending on the complexity of the desired manifestation, the clarity of the mental image, and the consistency of mental cultivation. Simple manifestations may appear quickly, while complex goals requiring multiple conditions to align may take months or years to fully develop according to this law.

Can the Law of Growth work negatively?

Yes, the Law of Growth operates impersonally and will develop whatever thoughts are consistently held in the subconscious mind, regardless of whether they are positive or negative. This is why New Thought teachers emphasize the importance of mental discipline and conscious control over one's thought patterns.

What role does the subconscious mind play in the Law of Growth?

The subconscious mind serves as the fertile soil where mental seeds grow according to the Law of Growth. Once the subconscious accepts a mental image, it works automatically to develop that image into corresponding external conditions through its connection to universal creative forces.
