The material opulences a person obtains by offering prayers to the goddess Durgā are temporary. As described in Bhagavad-gītā (7:23), antavat tu phalaḿteṣāḿ tad bhavaty alpa-medhasām: men of meager intelligence desire temporary happiness. We have actually seen that one of the disciples of Bhaktisiddhānta Sarasvatī Ṭhākura wanted to enjoy the property of his spiritual master, and the spiritual master, being merciful toward him, gave him the temporary property, but not the power to preach the cult of Caitanya Mahāprabhu all over the world. That special mercy of the power to preach is given to a devotee who does not want anything material from his spiritual master but wants only to serve him.

The story of the demon Rāvaṇa illustrates this point. Although Rāvaṇa tried to abduct the goddess of fortune Sītādevī from the custody of Lord Rāmacandra, he could not possibly do so. The Sītādevī he forcibly took with him was not the original Sītādevī, but an expansion of māyā, or Durgādevī. As a result, instead of winning the favor of the real goddess of fortune, Rāvaṇa and his whole family were vanquished by the power of Durgādevī (sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā [Bs. 5;44]).

Srimad Bhagavatam-10:1:69-purport:-The word kāryārthe refers to one who attracted the pregnancy of Devakī and bewildered mother Yaśodā. These pastimes are very confidential. The Supreme Personality of Godhead ordered yogamāyā to bewilder His associates in His pastimes and bewilder demons like Kaḿsa.

As stated previously,yogamāyāḿ samādiśat. To give service to the Lord, yogamāyā appeared along with mahāmāyā. Mahāmāyā refers to yayā sammohitaḿ jagat, "one who bewilders the entire material world." From this statement it is to be understood that yogamāyā, in her partial expansion, becomes mahāmāyā and bewilders the conditioned souls. In other words, the entire creation has two divisions — transcendental, or spiritual, and material. Yogamāyā manages the spiritual world, and by her partial expansion as mahāmāyā she manages the material world.

As stated in the Nārada-pañcarātra, mahāmāyā is a partial expansion of yogamāyā. The Nārada-pañcarātra clearly states that the Supreme Personality has one potency, which is sometimes described as Durgā. The Brahma-saḿhitā says, chāyevayasya bhuvanāni bibharti durgā [Bs.5:44]. Durgā is not different from yogamāyā. When one understands Durgā properly, he is immediately liberated, for Durgā is originally the spiritual potency, hlādinī-śakti, by whose mercy one can understand the Supreme Personality of Godhead very easily. Rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī-śaktir asmād [Adi 1.5]. The mahāmāyā-śakti, however, is a covering of yogamāyā, and she is therefore called the covering potency. By this covering potency, the entire material world is bewildered (yayā sammohitaḿ jagat).

In conclusion, bewildering the conditioned souls and liberating the devotees are both functions belonging to yogamāyā. Transferring the pregnancy of Devakī and keeping mother Yaśodā in deep sleep were both done by yogamāyā; mahāmāyā cannot act upon such devotees, for they are always liberated. But although it is not possible for mahāmāyā to control liberated souls or the Supreme Personality of Godhead, she did bewilder Kaḿsa. The action of yogamāyā in presenting herself before Kaḿsa was the action of mahāmāyā, not yogamāyā.Yogamāyā cannot even see or touch such polluted persons as Kaḿsa. In Caṇḍī, in the Mārkaṇḍeya Purāṇa, Eleventh Chapter, Mahāmāyā says, "During the twenty-eighth yuga in the period of Vaivasvata Manu, I shall take birth as the daughter of Yaśodā and be known as Vindhyācala-vāsinī."

Sri Caitanya Caritamrta-1:6:79-purport:-There are eleven expansions of Rudra, or Lord Śiva. They are as follows: Ajaikapāt, Ahibradhna, Virūpākṣa, Raivata, Hara, Bahurūpa, DevaśreṣṭhaTryambaka, Sāvitra, Jayanta, Pināki and Aparājita. Besides these expansions there are eight forms of Rudra called earth, water, fire, air, sky, the sun, the moon and soma-yājī. Generally all these Rudras have five faces, three eyes and ten arms. Sometimes it is found that Rudra is compared to Brahmā and considered a living entity. But when Rudra is explained to be a partial expansion of the Supreme Personality of Godhead, he is compared to Śeṣa.

Lord Śiva is therefore simultaneously an expansion of Lord Viṣṇu and, in his capacity for annihilating the creation, one of the living entities. As an expansion of Lord Viṣṇu he is called Hara, and he is transcendental to the material qualities, but when he is in touch with tamo-guṇa he appears contaminated by the material modes of nature. This is explained in Śrīmad-Bhāgavatam and the Brahma-saḿhitā. In Śrīmad-Bhāgavatam, Tenth Canto, it is stated that Lord Rudra is always associated with the material nature when she is in the neutral, unmanifested stage, but when the modes of material nature are agitated he associates with material nature from a distance.

In the Brahma-saḿhitā the relationship between Viṣṇu and Lord Śiva is compared to that between milk and yogurt. Milk is converted into yogurt by certain additives, but although milk and yogurt have the same ingredients, they have different functions. Similarly, Lord Śiva is an expansion of Lord Viṣṇu, yet because of his taking part in the annihilation of the cosmic manifestation, he is considered to be changed, like milk converted into yogurt. In the Purāṇas it is found that Śiva appears sometimes from the heads of Brahmā and sometimes from the head of Viṣṇu. The annihilator, Rudra, is born from Sańkarṣaṇa and the ultimate fire to burn the whole creation.

In the Vāyu Purāṇa there is a description of Sadāśiva in one of the Vaikuṇṭha planets. That Sadāśiva is a direct expansion of Lord Kṛṣṇa's form for pastimes. It is said that Sadāśiva (Lord Śambhu) is an expansion from the Sadāśiva in the Vaikuṇṭha planets (Lord Viṣṇu) and that his consort, Mahāmāyā, is an expansion of Ramā-devī, or Lakṣmī. Mahāmāyā is the origin or birthplace of material nature.

Srimad Bhagavatam-10:1:69:-purport:-The distinction between the two māyās — yogamāyā and mahā-māyā — is described as follows. Kṛṣṇa's rāsa-līlā with the gopīs and the gopīs' bewilderment in respect to their husbands, fathers-in-law and other such relatives were arrangements of yogamāyā in which mahāmāyā had no influence. The Bhāgavatam gives sufficient evidence of this when it clearly says, yogamāyām upāśritaḥ.

On the other hand, there were asuras headed by Śālva and kṣatriyas like Duryodhana who were bereft of devotional service in spite of seeing Kṛṣṇa's carrier Garuḍa and the universal form, and who could not understand Kṛṣṇa to be the Supreme Personality of Godhead. This was also bewilderment, but this bewilderment was due to mahāmāyā. Therefore it is to be concluded that the māyā which drags a person from the Supreme Personality of Godhead is called jaḍamāyā, and the māyā which acts on the transcendental platform is called yogamāyā. When Nanda Mahārāja was taken away by Varuṇa, he saw Kṛṣṇa's opulence, but nonetheless he thought of Kṛṣṇa as his son. Such feelings of parental love in the spiritual world are acts of yogamāyā, not of jaḍamāyā, or mahāmāyā. This is the opinion of Śrīla Viśvanātha Cakravartī Ṭhākura.
