"From the beginning of the manifestation He, by His internal potency, has been the cause and effect of all forms and the transcendental Absolute of the modes of nature. Although He, manifesting by the modes, having entered them, appears to be affected by the modes, He is the full manifestation of all wisdom. He, as the Supersoul, pervades all living beings as the source of creation like fire does in wood and shines forth as different living entities, at the same time being the Absolute Person. That Supersoul, created the subtle senses influenced by the modes of nature by entering the living beings in His own creation, causing them to enjoy those modes. Thus He maintains all of them in the mode of goodness, being incarnated Himself in the performance of His pastimes as the master of all the worlds of the divine, human and animalistic beings."
"The learned souls say that the reality of nondual knowledge is known as Brahman, Paramâtmâ and Bhagavân [the impersonal, localized and personal aspect]."
"He whose incarnations and activities we glorify, He who by persons like us cannot be fully known, is the Supreme Lord whom we offer our respectful obeisances. He, the Primordial Original Personality millennium after millennium creates within Himself, by Himself, His Self [the universe] maintains Himself [for some time] and absorbs [Himself again]. Without a material tinge, pure and perfect in knowledge and all-pervading in His fullness, He is situated in truth as the absolute without a beginning and an end, free from the qualities of nature, eternal and without an equal. Oh wise one, the great thinkers can only understand this with a pacified self and their senses at rest, otherwise it will certainly be beyond their scope and be distorted by time-bound arguments. The first avatâra of the Lord is the Original Person: [Mahâvishnu or Kâranodakas'âyî Vishnu. He is the foundation of] space time [kâla svabhavah, the original nature of time], cause, effect, the elements, the modes, as also the ego, the senses and the mind. These together constitute the diversity of the gigantic universal independent body [also called Garbhodakas'âyî Vishnu] of all that moves and does not move of the Almighty Supreme."
"Maitreya said: 'It [Eternal Time] is the source of the different [organic and anorganic] interactions of the modes of nature, it is undivided and unlimited and it is the instrument of the Original Person to create, by His pastimes, the material life of the soul. It is by means of time [kâla], the hidden, impersonal feature, that the Lord separated from the Supreme Absolute [God or brahma] the material phenomenon that was established as the bewildering material potency of Vishnu. The way it [Eternal Time] is there in the present, it was there in the beginning and will also be there hereafter."
"All this I enumerated - earth, air, sky, water and fire, the ego, the greater [principle, the intellect], the [additional eleven] transformations [the ten indriyas and the mind], the person, that what is unmanifest and the modes of rajas, tamas and sattva - stands together with the spiritual knowledge and the steady conviction [therewith] for Me, I the One Supreme. I, the Supreme Lord, the living entity, the [good] qualities and the possessor of the qualities, am the Soul of all; I am indeed everything, the one outside of whom nothing whatsoever exists. I who create the universes by the millions, may count their atoms after a certain time, but not so My opulences [compare 10.14: 7]. Whatever power, beauty, fame, dominion [see 11.15], humility, renunciation, enjoyment, fortune, strength, tolerance or wisdom one may find, all constitutes an integral part of Me."
To say that Krishna as the Supreme God is an invention of newer sects shows a lot of ignorance on Hinduism.
