Lord Krsna - source of all avatars and expansions and cause of all causes

Lord Krishna is the Supreme Personality of Godhead and the cause of all causes.

He is the source of all expansions -  Vishnu Tattva, Shiva Tattva, Shakti Tattva, Jiva Tattva.

Krishna is the only Personality that has all 64 qualities in full which is 100% of all His own Individual Self.

This makes Krishna the Supreme Personality of Godhead and cause of all that there is.

Vishnu Tattva and the other eternal associates in both Vaikuntha and Goloka Vrindavana  known as Shakti Tattva. Both have 93% and can never be covered by Maya (Material energy) and appear in many different Forms

Shiva Tattva has 84% and is in a unique mysterious league of His own.

Jiva Tattva like us and includes Lord Brahma and Narada Muni all have 78%

Lord Krishna.          64 qualities or 100%
Vishnu Tattva.          60 qualities or ~93%
Shiva Tattva.             54 qualities or ~84%
Jiva Tattva.               50 qualities or ~78%

The Supreme Personality of Godhead Lord Krishna has all these fifty transcendental qualities in fullness as deep as the ocean.

In other words, the extent of His qualities is inconceivable.

Besides all of the above-mentioned fifty qualities, Lord Krishna possesses five more, which are sometimes partially manifested in Lord Brahma or Lord Shiva. These transcendental qualities are as follows:

(51) Changeless
(52) all-cognizant
(53) Ever fresh
(54) sac-cid-ananda (possessing an eternal blissful body)
(55) Possessing all mystic perfections.

Krishna also possesses five other qualities, which are manifest in the body of Narayana / Vishnu, and they are listed as follows:

(56) He has inconceivable potency.
(57) Uncountable universes generate from His body.
(58) He is the original source of all incarnations.
(59) He is the giver of salvation to the enemies whom He kills.
(60) He is the attractor of liberated souls.

Besides these sixty transcendental qualities, Krishna has four more, which are not manifested even in the Vishnu / Narayana form of Godhead, what to speak of the demigods or living entities. They are as follows:

(61) He is the performer of wonderful varieties of pastimes (especially His childhood pastimes).
(62) He is surrounded by devotees endowed with wonderful love of Godhead.
(63) He can attract all living entities all over the universes by playing on His flute.
(64) He has a wonderful excellence of beauty which cannot be rivaled anywhere in the creation.

The Absolute Truth is anandamaya (desiring to increase His joy), hence from His original form He expands and becomes many.

These emanations from the Supreme Person are of two categories: full expansions and partially manifested expansions.

The Lord's various full and partial expansions and the Lord Himself simultaneously co-exist, only appearing to manifest under the influence of time.

These expansions of the Supreme Being are known as Vishnu-tattva, and they are also Supreme Absolute Truth.

While non-different from the Lord, the Vishnu-tattvas all accept their own role as Godhead in the mood of Servitor to the "original" Supreme Being.

This relationship is the foundation of Vedic monotheism, which encompasses the inconceivable, absolute personal nature of the original Godhead.

The Supreme Being possesses two other expansive qualities known as Shiva-tattva and jiva-tattva.

Together with Vishnu-tattva, these three qualities are representative of the Absolute Person's internal, external and marginal energies.

The Lord has expanded Himself as Lord Shiva and Lord Brahma, and we, the living entities, are also expansions. Like us, Lord Brahma is also jiva-tattva.

Lord Siva is between Vishnu-tattva and jiva-tattva. And Lord Visnu is Vishnu-tattva. Vishnu-tattva, via media, and jiva-tattva - they are all expansions of the Supreme Personality of Godhead.

Therefore we can summarize as

Lord Krishna.          64 qualities or 100%
Vishnu Tattva.          60 qualities or ~93%
Shiva Tattva.             54 qualities or ~84%
Jiva Tattva.               50 qualities or ~78%

This is the reason why Krishna is called Param Purushottam, Purnavatar or Supreme Personality of Godhead.

Reference from (Srimad Bhagavatam 1.3.29):

Learned scholars in transcendental subjects have carefully analyzed the summum bonum Krsna to have sixty-four principal attributes.

All the expansions or categories of the Lord possess only some percentages of these attributes. But Sri Krsna is the possessor of the attributes cent percent.

And His personal expansions such as svayam-prakasa, tad-ekatma up to the categories of the avataras who are all visnu-tattva, possess up to ninety-three percent of these transcendental attributes.

Lord Siva, who is neither avatara nor avesa nor in between them, possesses almost eighty-four percent of the attributes.

But the jivas, or the individual living beings in different statuses of life, possess up to the limit of seventy-eight percent of the attributes.

In the conditioned state of material existence, the living being possesses these attributes in very minute quantity, varying in terms of the pious life of the living being.

The most perfect of living beings is Brahma, the supreme administrator of one universe. He possesses seventy-eight percent of the attributes in full.

All other demigods have the same attributes in less quantity, whereas human beings possess the attributes in very minute quantity.

The standard of perfection for a human being is to develop the attributes up to seventy-eight percent in full.

The living being can never possess attributes like Siva, Visnu or Lord Krsna.

A marginal living being (jiva tattva) can become godly by developing the seventy-eight-percent transcendental attributes in fullness, but the jiva tattva can never become a God like Shiva, Visnu or Krsna.

The jiva tattva can become a Brahma in due course.

The godly living beings who are all residents of the planets in the spiritual sky are eternal associates of God in different spiritual planets called Hari-dhama and Mahesa-dhama.

The abode of Lord Krsna above all spiritual planets is called Krsnaloka or Goloka Vrndavana, and the perfected living being, by developing seventy-eight percent of the above attributes in fullness, can enter the planet of Krsnaloka after leaving the present material body in the material creation and stay there "if they choose".

The jiva tattva always has "free will and the ability to choose" in its full potential be it either in the material world or Spiritual Planets.
