Although all the visnu-tattvas, from Krsna and Lord Caitanya to Rama, Nrsimha, Varaha and so on, appear with different features in different ages, all are equally invested with supreme potency
The word "aṅga" indeed refers to plenary portions. Such manifestations should never be considered products of material nature, for they are all transcendental, full of knowledge and full of bliss.
In the material world, if a fragment is taken from an original object, the original object is reduced by the removal of that fragment. But the Supreme Personality of Godhead is not at all affected by the actions of māyā. The Īśopaniṣad says:
- oṁ pūrṇam adaḥ pūrṇam idaṁ
- pūrṇāt pūrṇam udacyate
- pūrṇasya pūrṇam ādāya
- pūrṇam evāvaśiṣyate
"The Personality of Godhead is perfect and complete, and because He is completely perfect, all emanations from Him, such as this phenomenal world, are perfectly equipped as complete wholes. Whatever is produced of the complete whole is also complete in itself. Because He is the complete whole, even though so many complete units emanate from Him, He remains the complete balance." (Śrī Īśopaniṣad, Invocation)
In the realm of the Absolute, one plus one equals one, and one minus one equals one. Therefore one should not conceive of a fragment of the Supreme Lord in the material sense. In the spiritual world there is no influence of the material energy or material calculations of fragments. In the Fifteenth Chapter of the Bhagavad-gītā, the Lord says that the living entities are His parts and parcels. There are innumerable living entities throughout the material and spiritual universes, but still Lord Kṛṣṇa is full in Himself. To think that God has lost His personality because His many parts and parcels are distributed all over the universe is an illusion. That is a material calculation. Such calculations are possible only under the influence of the material energy, māyā. In the spiritual world the material energy is conspicuous only by its absence.
In the category of viṣṇu-tattva there is no loss of power from one expansion to the next, any more than there is a loss of illumination as one candle kindles another. Thousands of candles may be kindled by an original candle, and all will have the same candle power. In this way it is to be understood that although all the viṣṇu-tattvas, from Kṛṣṇa and Lord Caitanya to Rāma, Nṛsiṁha, Varāha and so on, appear with different features in different ages, all are equally invested with supreme potency.
Demigods such as Lord Brahmā and Lord Śiva come in contact with the material energy, and their power and potency are therefore of different gradations. All the incarnations of Viṣṇu, however, are equal in potency, for the influence of māyā cannot even approach Them.
