Contemplation on Verses 2.42-44 - in light of Mundaka Upanisad (1st Mundaka, 2nd Section)
Sri Krishna's critical view of those who take delight in the Kamya Karma, quoting the Vedas as the basis for thier actions and goals - is seen in Upanisad itself. Mundaka Upanisad - 1st Mundaka - 2nd Section is entirely devoted to this line of thought. This section spends about 6-7 verses outlining the nature of Karma undertaken by those desirous of heavenly pursuit. (These are very instructive, information verses in general). Verse 1.2.6 clearly outlined the end-destination of one - who manages to successfully perform these difficult karmas with precision. एह्येहीति तमाहुतयः सुवर्चसः सूर्यस्य रश्मिभिर्यजमानं वहन्ति। प्रियां वाचमभिवदन्त्योऽर्चयन्त्य एष वः पुण्यः सुकृतो ब्रह्मलोकः।।1.2.6।। English Translation By Swami Gambirananda ।।1.2.6।।.Saying, ‘ Come, come ’, uttering pleasing words such as, ‘ This is your well-earned, virtuous path which leads to heaven ’, and offering him adoration, the scintillating oblations carry the sacrificer along the rays of the sun.
