Yoga is Harmony with the Self & the Universe

Sutra 2: The restraint of the modifications of the mind-stuff is Yoga

It is the goal of the yogi to transform themselves from a limited physical, mental, and emotional person into a completely illuminated, harmonized, and perfected being. In class we explored these concepts with different exercises and challenges which really helped us to see the difficulty in achieving these goals. The last two challenges of meditation and reflecting or meditating on our attachments were particularly important to the concept of being in harmony with one’s self and the universe.

Another sutra that emphasizes this point of harmonizing with the self and the universe through yoga is sutra 16: When there is non-thirst for even the gunas (constituents of Nature) due to realization of the Purusha (true Self), that is supreme non-attachment. In this sutra, Patanjali is trying to explain the detachment of the mind from its personal desires and enjoyment is the ordinary vairagya, which is disinterest in things that would cause attachment in people. This was again one of our challenges in class to reflect on our attachments both good and bad and see if we can eliminate them from our lives.
Through the yogic practice of meditation and the elimination of attachments to understand your true Self is how you achieve harmony with yourself and the universe. 
Meditation allowed us to look deeper at ourselves and concentrate on what would bring us eternal peace. Reflecting on our attachments (both good and bad attachments) we could then see what we needed to eliminate from our lives in order to better understand ourselves and the world around us as well as trying to achieve harmony with both.
