Link:- After hearing the Lord's order to behold His cosmic form, Arjuna may be curious to know where to behold it. So the Lord declares.
ihaikastham jagatkrtsnam pasyadya sacaracaram
mama dehe gudakesa yaccanyaddrastumicchasi
O conqueror of sleep Arjuna, now behold within this body of Mine, the entire universe consisting of both animate and inanimabeings and whatever else you wish to see. 7
An Important Fact
Gudakesa:- Arjuna is addressed as 'Gudakesa because he was the conqueror of sleep. The Lord by addressing Arjuna as Gudakesa, invites him to observe His cosmic form, attentively giving up indolence.
Ihaikastham jagatkrtsnam pasyadya sacarscaram mama dehe:- At the end of the tenth chapter, the Lord declared, that He supports the whole universe, with a single fragment of His self. So, Arjuna developed a desire to see his cosmic form. Therefore, the Lord calls upon Arjuna to behold, within a part of His body the entire creation, consisting of both animate and inaniruate beings, while He is sitting in front of him with the horses bridle and a whip, in His hands. The Lord says that in His body, wherever he looks, he will see, infinite universes. The word 'Cara' stands for all creatures possessing mobility, such as men, gods, genies, demons, ghosts, beasts and birds etc., while 'Acara', denotes things devoid of motion, such as trees, plants and hills etc., and 'Adya', here means now. The Lord means to say, that there is no reason for any delay, for Him to reveal His cosmic form. So He reveals it, the moment Arjuna expresses his earnest desire to behold it.
Yaccanyaddrastumicchasi:- By this expression, Lord Krsna wants to convey to Arjuna, that he can perceive, not only the incidents relating to the present, but also of the past, and the future. Moreover, Arjuna had a doubt, whether they would win the war or the Kauravas, would (Gita 2/6). So Lord Krsna asks him to perceive at that ruoment, in a part of His body, a scene of his own victory, and his enemy's defeat.
The Lord, in the seventh verse of the tenth chapter, declared, "He who knows in reality, the divine glory and power of Mine, is endowed with, unfaltering Yoga of devotion.
