When we contemplated on deeper issues of life contained in Bhagavad Gita, we realized that voice of Lord Krishna coming from within our heart is actually the voice of God Almighty himself getting relayed through Lord Krishna, the soul atman within.
When a TV transmission starts from Central Station in New Delhi, its first gets relayed to repeater station at Mussoorie for onward transmission to Roorkee. If a person goes from New Delhi to Mussoorie one has to pass through Roorkee. But the TV signal does not directly come to Roorkee first but via Mussoorie.
The same is the case with cosmic transmission by God Almighty. All transmissions of God Almighty to independent soul atmans were through Lord Krishna, the spirit soul atman existing in our heart. If Lord Krishna says I am the death and controller of life on mother earth, it was God Almighty, Brahman in Hinduism saying that. Lord Krishna was only the medium in between.
In simpler terms we can say Lord Krishna represents God Almighty on mother earth. The wisest person who was nearest to God on mother earth was Lord Krishna. An avatar in Hinduism (God manifest in human form) is closest to God, even closer than man gods like Mahavira, Gautama Buddha even Jesus Christ and Prophet Mohammed.
To understand everything explained above one has to dive deep into the bottomless pit of wisdom contained in Bhagavad Gita via path of contemplation. Unless one mastered the art of contemplation, nothing in field of spirituality can be correctly understood.
Becoming 100% truthful, believing in God and world of souls’ atmans and further demolishing our ego in totality seekers can come closer to God and finally merge with him in totality. This is what Bhagavad Gita is all about, showing a path to reaching God in our lifetime!
