Bhagavad Gita : अध्याय 18 का श्लोक 26
मुक्तसङ्गोऽनहंवादी धृत्युत्साहसमन्वितः ।सिद्धयसिद्धयोर्निर्विकारः कर्ता सात्त्विक उच्यते॥
भावार्थ : जो कर्ता संगरहित, अहंकार के वचन न बोलने वाला, धैर्य और उत्साह से युक्त तथा कार्य के सिद्ध होने और न होने में हर्ष -शोकादि विकारों से रहित है- वह सात्त्विक कहा जाता है ॥26॥
The worker who is free from all material attachments and false ego, who is enthusiastic and resolute and who is indifferent to success or failure, is a worker in the mode of goodness.
A person in Kṛṣṇa consciousness is always transcendental to the material modes of nature. He has no expectations for the result of the work entrusted to him because he is above false ego and pride. Still, he is always enthusiastic till the completion of such work. He does not worry about the distress undertaken; he is always enthusiastic. He does not care for success or failure; he is equal both in distress or happiness. Such a worker is situated in the mode of goodness.
