Sankhya Yoga
सांख्ययोग
In plain words
You are being guided to perform all your duties with a balanced mind, completely letting go of attachment to success or failure. This inner stability is the heart of yoga. By remaining calm and steady through life's ups and downs, you purify your heart and align your actions with your highest spiritual dharma, your sacred duty.
Translation
2.48 Abandoning attachment and established in Yoga, perfom works, viewing success and failure with an even mind. Evenness of mind is said to be Yoga.
Meaning
Dwelling in union with the Divine perform actions merely for Gods sake with a balanced mind in success and failure. Eilibrium is Yoga. The attainment of the knowledge of the Self through purity of heart obtained by doing actions without expectation of fruits is success (Siddhi). Failure is the nonattainment of knowledge by doing actions with expectation of fruit. (Cf. III.9IV.14IV.20).
