Had Lord Krishna power to dissolve present cosmos and create a new one? Could Lord Krishna create something out of nothing? Can Brahman be of human form, one made of flesh and bones?
How could we be so naive ignorant in matters spiritual?
Brahman is pure primordial cosmic energy beyond comprehension of human intellect? None in this world in the past or present or future would ever be able to comprehend the enormity of Brahman, the one and only God, creator of entire cosmos.
Yes, the sum total of all souls’ atmans in cosmos in their pure form is what we called God Almighty, Brahman in all its glory.
Whenever Lord Krishna in Bhagavad Gita talks of Brahman he uses the word I for he is invoking powers of Brahman by tuning in him through Shruti jnana. Any human being after reaching state of enlightenment, self realization god realization can tune into God Almighty every second of life, something we called communion with God Almighty on one-to-one basis.
If Lord Krishna says, whenever there is downfall of the society, I shall manifest again and again as an avatar to re-establish Dharma (righteousness). This simply means, in times of extreme strife, tribulation one amongst us dons mantle of Lord Krishna, an avatar of his era. As Brahman never manifests himself he sends a representative on mother earth in form of an avatar.
We are presently facing Kali Yuga (Dark Age) whence almost similar conditions exist as during times of Lord Krishna in Dwapar Yuga. After a gap of above 3650 years mankind would witness advent of Kalki avatar, the annihilator of Kali Yuga, ne who shall successfully re-establish Dharma (righteousness) in present times.
It is not even a decade before Kalki avatar surfaces.
Literally studying Bhagavad Gita never leads anywhere, we can reach the hidden underlying meanings of sacred texts contained in Bhagavad Gita only by contemplation (indulging in chintan) every given moment of life. But contemplation is something difficult to visualize, indulge prime reason why most human beings world over preferred the easy path of religion (rituals) knowing well that following religion none ever reached god.
If we seriously desire knowing everything relating to Brahman, God then we have to master the delicate art of contemplation (chintan).
