Let us see what the ancient Yogi’s who are the authentic source of the Yogic science had to say about Yoga.
“Yogah Karmasu Kaushalam” from BHAGWAD GITA Chapter 2 Verse 50
Yoga is skill in action, Lord Krishna says in Bhagwad Gita. Giving yourself fully in any action that you do. Giving your cent percent. Becoming one with the activity you are performing while being relaxed in the midst of the activity is Yoga. Though, you are fully engaged in the work, you are not attached to its fruits..
“Samatvam Yoga Uchyate” from BHAGWAD GITA Chapter 2 Verse 50
Yoga is staying even in success and failures, in sadness, and happiness and in the ups and downs of your life. You have a smile when you are happy, if this continues when you are sad, then that is Yoga.
“Yogas Chitta Vritti Nirodhah” from PATANJALI YOGA SUTRA SHLOKA #2
Yoga is when all the activities of the mind have stopped. It is a state of complete dissolution of the mind. Other way this aphorism can be understood is that, Yoga is when You are the controller of the activities that goes on in the mind. The mind is no longer ruling You, but You are the king ruling your mind. Usually you are swayed by your senses, which is a good friend of the mind. The mind works as per them mostly. Yoga is when You are no longer a slave to your senses.
“Manah Prasamanopayah Yoga ityabhidhiyate” from YOGA VASISTHA
Calming down the mind skilfully is Yoga. There are two ways to have a mastery over the mind. One is by concentration or one-pointed attention, other way is by silencing the actives of the mind. Usually in today’s modern world, everyone focuses on the first aspect of mastery over the mind, but rarely there are people who can silence the mind at will or even attain it by chance. Yoga is the skilful method of soothing the mind.
