being, knowledge and bliss.” Impersonal Brahman realization is the realization of His  sat  (being) feature. Paramātmā realization is the realization of the  cit  (eternal knowledge) feature. But realization of the Personality of Godhead, Kṛṣṇa, is realization of all the transcendental features:  sat ,  cit  and  ānanda  (being, knowledge, bliss) in complete  vigraha  (form).
People with less intelligence consider the Supreme Truth to be impersonal, but He is a transcendental person, and this is confirmed in all Vedic literatures.  Nityo nityānām cetanaś cetanānām . As we are all individual living beings and have our individuality, the Supreme Absolute Truth is also, in the ultimate issue, a person, and realization of the Personality of Godhead is realization of all of the transcendental features. The complete whole is not formless. If He is formless, or if He is less than any other thing, then He cannot be the complete whole. The complete whole must have everything within our experience and beyond our experience, otherwise it cannot be complete. The complete whole, Personality of Godhead, has immense potencies.
How Kṛṣṇa is acting in different potencies is also explained in  Bhagavad-gītā . This phenomenal world or material world in which we are placed is also complete in itself because the twenty-four elements of which this material universe is a temporary manifestation, according to Sāṅkhya philosophy, are completely adjusted to produce complete resources which are necessary for the maintenance and subsistence of this universe. There is nothing extraneous; nor is there anything needed. This manifestation has its own time fixed by the energy of the supreme whole, and when its time is complete, these temporary manifestations will be annihilated by the complete arrangement of the complete. There is complete facility for the small complete units, namely the living entities, to realize the complete, and all sorts of incompleteness are experienced due to incomplete knowledge of the complete. So  Bhagavad-gītā  contains the complete knowledge of Vedic wisdom.
All Vedic knowledge is infallible, and Hindus accept Vedic knowledge to be complete and infallible. For example, cow dung is the stool of an animal, and according to  smṛti , or Vedic injunction, if one touches the stool of an animal he has to take a bath to purify himself. But in the Vedic scriptures cow dung is considered to be a purifying agent. One might consider this to be contradictory, but it is accepted because it is Vedic injunction, and indeed by accepting this, one will not commit a mistake; subsequently it has been proved by modern science that cow dung contains all antiseptic properties. So Vedic knowledge is complete because it
