Bhagavad Gita : अध्याय 18 का श्लोक 6
एतान्यपि तु कर्माणि सङ्गं त्यक्त्वा फलानि च ।कर्तव्यानीति में पार्थ निश्चितं मतमुत्तमम् ॥
भावार्थ : इसलिए हे पार्थ! इन यज्ञ, दान और तपरूप कर्मों को तथा और भी सम्पूर्ण कर्तव्यकर्मों को आसक्ति और फलों का त्याग करके अवश्य करना चाहिए, यह मेरा निश्चय किया हुआ उत्तम मत है ॥6॥
All these activities should be performed without any expectation of result. They should be performed as a matter of duty, O son of Pṛthā. That is My final opinion.
Although all sacrifices are purifying, one should not expect any result by such performances. In other words, all sacrifices which are meant for material advancement in life should be given up, but sacrifices that purify one's existence and elevate one to the spiritual plane should not be stopped. Everything that leads to Kṛṣṇa consciousness must be encouraged. In the Śrīmad-Bhāgavatam also it is said that any activity which leads to devotional service to the Lord should be accepted. That is the highest criterion of religion. A devotee of the Lord should accept any kind of work, sacrifice, or charity which will help him in the discharge of devotional service to the Lord
