Gita Chapter 11.41 to 11.45

Sakheti matwaa prasabham yaduktam
He krishna he yaadava he sakheti;
Ajaanataa mahimaanam tavedam
Mayaa pramaadaat pranayena vaapi.
41. Whatever I have presumptuously uttered from love or carelessness, addressing Thee as O Krishna! O Yadava! O Friend! regarding Thee merely as a friend, unknowing of this, Thy greatness,

Yachchaavahaasaartham asatkrito’si
Vihaarashayyaasanabhojaneshu;
Eko’thavaapyachyuta tatsamaksham
Tatkshaamaye twaamaham aprameyam.
42. In whatever way I may have insulted Thee for the sake of fun while at play, reposing, sitting or at meals, when alone (with Thee), O Achyuta, or in company—that I implore Thee, immeasurable one, to forgive!

Pitaasi lokasya charaacharasya
Twamasya poojyashcha gururgareeyaan;
Na twatsamo’styabhyadhikah kuto’nyo
Lokatraye’pyapratimaprabhaava.
43. Thou art the Father of this world, unmoving and moving. Thou art to be adored by this world. Thou art the greatest Guru; (for) none there exists who is equal to Thee; how then can there be another superior to Thee in the three worlds, O Being of unequalled power?

Tasmaatpranamya pranidhaaya kaayam
Prasaadaye twaamahameeshameedyam;
Piteva putrasya sakheva sakhyuh
Priyah priyaayaarhasi deva sodhum.
44. Therefore, bowing down, prostrating my body, I crave Thy forgiveness, O adorable Lord! As a father forgives his son, a friend his (dear) friend, a lover his beloved, even so shouldst Thou forgive me, O God!

Adrishtapoorvam hrishito’smi drishtwaa
Bhayena cha pravyathitam mano me;
Tadeva me darshaya deva roopam
Praseeda devesha jagannivaasa.
45. I am delighted, having seen what has never been seen before; and yet my mind is distressed with fear. Show me that (previous) form only, O God! Have mercy, O God of gods! O abode of the universe!

Gita Chapter 2.36 to 2.40

Avaachyavaadaamshcha bahoon vadishyanti tavaahitaah;
Nindantastava saamarthyam tato duhkhataram nu kim.
36. Thy enemies also, cavilling at thy power, will speak many abusive words. What is more painful than this!

Hato vaa praapsyasi swargam jitwaa vaa bhokshyase maheem;
Tasmaad uttishtha kaunteya yuddhaaya kritanishchayah.
37. Slain, thou wilt obtain heaven; victorious, thou wilt enjoy the earth; therefore, stand up, O son of Kunti, resolved to fight!

Sukhaduhkhe same kritwaa laabhaalaabhau jayaajayau;
Tato yuddhaaya yujyaswa naivam paapamavaapsyasi.
38. Having made pleasure and pain, gain and loss, victory and defeat the same, engage thou in battle for the sake of battle; thus thou shalt not incur sin.
COMMENTARY: This is the Yoga of equanimity or the doctrine of poise in action. If a person performs actions with the above mental attitude, he will not reap the fruits of such actions.

Eshaa te’bhihitaa saankhye buddhir yoge twimaam shrinu;
Buddhyaa yukto yayaa paartha karma bandham prahaasyasi.
39. This which has been taught to thee, is wisdom concerning Sankhya. Now listen to wisdom concerning Yoga, endowed with which, O Arjuna, thou shalt cast off the bonds of action!

Nehaabhikramanaasho’sti pratyavaayo na vidyate;
Swalpam apyasya dharmasya traayate mahato bhayaat.
40. In this there is no loss of effort, nor is there any harm (the production of contrary results or transgression). Even a little of this knowledge (even a little practice of this Yoga) protects one from great fear.
COMMENTARY: In Karma Yoga (selfless action) even a little effort brings immediate purification of the heart. Purification of the heart leads to fearlessness.
