Tatra sthitau yatnah abhyasah.
Effort toward steadiness is practice.
Yoga Sutras 1.13
Everyone it seems, struggles with the "for a long time, without a break and in all earnestness" definition of a well grounded Yoga practice from Patanjali. But, the student asked, if a person chooses actions that are consistent with a spiritual practice and is making an effort to elevate their inner consciousness, isn't this also a practice?
In my opinion, while seeking to grow and to be a better person is good and positive, what separates this ambition from Sadhana or Abhyasah is the use of a system to reach that goal. Yogis use some system or systems like Tantra, Hatha Yoga, Raja Yoga, Karma Yoga, etc. and in addition to using a system, they also maintain some schedule with the system. A Yogi with a dedicated practice knows that they do this technique for 30 minutes every day and that technique 3 times per week- the work is not free form or just when we feel like it. Why do we practice this way? Because it works. Maintaining a practice schedule adds just a bit of austerity to the Yogi's life. The fire of Tapas is transformative and mighty powerful.
It is said that there are 2 ways to achieve the enlightened state: Practice and Grace. One way is through a system and a schedule and the other way is by Divine Grace- a boon or gift from the Universe.
I often think of my grandmother, Lois, as a Yogi without a Yogic practice. She is someone in my life that I have admired and tried to emulate. When you walked into her house, you felt loved. She was eternally cheerful, could tell a good story, loved to laugh, could cook up some amazing southern food, was an accomplished gardener and a natural healer. She would often do some calisthenics as she called them for exercise outside in the mornings. She had a long, happy marriage and produced 10 children and many grandchildren. She never went to church, but she was reverent and spiritual and tried to see the good in people. I happen to love stones and rocks. I actually see and feel the life force in them. I see them as stone "people". I learned to love stones from Lois. We often went on hikes with her and she always returned home with pockets and handfuls of natural treasures- rocks, flowers, Indian arrow heads, feathers, pine cones and often, produce from her large garden. The sacred objects were displayed over the sink on a sunny windowsill and the produce was gobbled up on the way home. She seemed to possess that state of contentment that I seek, yet, when I look for spiritual teachers, I specifically look for those who have accomplished the exalted state through a system so that they are able to teach the method for the path. One of my teachers says that practicing Yoga without a teacher is like building a house by yourself. It might be possible, but wouldn't it be more efficient to get some help from someone who has done it before?
On this path no effort is wasted,
no gain is ever reversed;
even a little of this practice
will shelter you from great sorrow.
Bhagavad Gita 2.40
