Yoga Philosophy: Exploring Patanjali's Yoga Sutras

Sandeep Gupta



Yoga is a belief system that promotes mindfulness through a mix of movement and meditation. As yoga's popularity has grown around the world, there's been a shift in focus on yoga as simply asanas (poses and movement).

But that's not all there is to yoga.

In my yoga philosophy class on myYogaTeacher, we'll explore the Patanjali Yoga Sutras. I encourage you to sign up for a free two-week trial of myYogaTeacher and join me! In addition to the yoga philosophy class, you'll get access to more than 35 live, online yoga classes with a variety of styles and teachers.

Here, we'll be taking a brief look at who Patanjali was, what the Yoga Sutras are, and why it's so important to know about this side of yoga.

Who Was Patanjali?

Patanjali (also known as Gonardiya or Gonikaputra) was the author of the Yoga Sutras. These works first gained prominence in the 2nd century BCE and again in the 5th century CE. In addition to the Yoga Sutras, which we'll look at in this article, Patanjali is also credited as being the author, or one of the authors, of Mahabhashya, a defense of grammarian Panini against his main critic Katyayana.

What Are the Four Yoga Sutras?

List of Four Yoga Sutras

Written by Patanjali, the Yoga Sutras is one of the classic yoga texts and introduced Patanjali's understanding of the Eight Limbs of Yoga. It was originally written in Sanskrit and, despite not even covering the asanas we've learned to associate with yoga, is the most popular and well-recognized techniques for training your body and expanding your mind.

The entire book is a collection of 196 aphorisms that cover everything from art to science to the philosophy of life. It consists of four chapters:

  • Samadhi: You are a soul; you have a body
  • Sadhana: The actions you should take
  • Vibhuti: The mystic powers gained through yoga practice
  • Kaivalya: Self-realization

Each attempt to learn the meaning of the Yoga Sutras is said to bring you a step closer to true enlightenment.

Let's look at each of the four chapters more closely.


The first chapter of the Yoga Sutras is Samadhi. It includes 51 sutras and teaches you the foundation of what you need to know about yoga, obstacles to overcome, the importance of abhyasa (constant practice), and vairagya (the detachment from material experiences and worldly pleasures).

Samadhi gets into how the mind works as well as how you can bring peace and calm to your mind with an understanding of mental activities such as:

  • Pramana: Good thoughts and true knowledge
  • Viparyaya: Bad thoughts and wrong understanding
  • Vikalpa: Confusion
  • Nidra: Sleep while the mind remains active
  • Smriti: Memory or using the senses of smell, touch, sight, taste

Patanjali tells us that we can restrict these mental activities through abhyasa and vairagya.


The Eight Limbs of Yoga

The second chapter of the Yoga Sutras is Sadhana. In this chapter, Patanjali introduces the principles of Ashtanga yoga, Kriya yoga, and Karma as well as the Eight Limbs of Yoga:

  • Yamas: Ethical standards (Ahimsa—non-violence; Satya—truthfulness; Asteya—not stealing; Brahmacharya—celibacy or not over-indulging; and Aparigraha—lack of ego)
  • Niyamas: Self-discipline (Shaucha—purity; Santosha—contentment; Tapa—fortitude; Svadhyaya—study; Ishvara-pranidhana—devotion to God or your own higher self)
  • Asana: Yoga postures
  • Pranayama: Breath control
  • Pratyahara: Withdrawal
  • Dharana: Concentration
  • Dhyana: Single focus
  • Samadhi: Total self-collectedness


The third chapter of the Yoga Sutras is Vibhuti. In this chapter, Patanjali discusses how Dharana, Dhyana, and Samadhi are all connected and pays particular attention to Dhyana and Samadhi.

Dharana means fixing your focus on a single object. Then, focusing and concentrating your mind on the object becomes Dhyana. When the object, and only the object, fills your consciousness entirely, that's Samadhi.

You'll notice that this sounds a lot like meditation. Many times, Dhyana is misinterpreted as "meditation," but it's not exactly the meditation we're familiar with these days. Dhyana is what happens when you can't separate a sense of self from the act of meditation or really even perceive it.

Dharana is actually closer to what we understand modern meditation to be. Through the practice of Dharana, we can better understand our minds, their patterns, and notice the thoughts that interrupt us.


The final chapter of the Yoga Sutras is Kaivalya. In this chapter, Patanjali reflects on the mind's achievements and prepares you for moksha (complete liberation). This liberation comes from the separation of the soul (Purusha) from the source (Prakriti). While separation is often seen as a bad or scary thing, in this case, the soul no longer experiences the misery that comes from this connection.

Why Bother With Yoga Philosophy?

Now you know a bit more about yoga philosophy and you may be wondering if it really matters? Does knowing more about yoga philosophy really make a difference to your practice?

The answer, as with most things, is "it depends."

Here are three key reasons I think it's important to study Patanjali's Yoga Sutras.

  • Connect to Your Yoga Roots: If you practice yoga, you're part of a yoga lineage. Your yoga teacher learned from a teacher who learned from a teacher, and so on. These lineages can be traced back centuries. Studying texts like the Yoga Sutras can help you stay connected to your yoga lineage and achieve a deeper, more authentic practice.
  • Figure Out What's Holding You Back: Through the Yoga Sutras, you can better understand how your thoughts hold you back and keep you from living your best, most satisfying life.
  • Let Go of Suffering: While asanas have many health benefits, a complete yoga practice can do so much more for you. According to Patanjali, yoga chitta vritti nirodhah, "yoga is the stilling of the fluctuations of the mind." Through discovering and understanding that you are complete as you are, you can start to let go of your suffering.

Build a Practice You Believe In With Yoga Philosophy

In Western culture, yoga has been distilled into a simple practice of poses and meditation, but yoga is so much more than that. When you learn about the roots of yoga, you can develop a more authentic practice that will not only improve your physical, mental, and emotional health but can transform your life.
