In their philosophical discussions the Māyāvādīs deny the existence of the Supreme Lord's multifarious energies. Such sub-standard debates are indeed on the kindergarten level. According to Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura, the Māyāvādīs have a poor fund of knowledge and are thus prevented from understanding that the Supreme Brahman is full with six opulences. To save these poor Māyāvādī impersonalists from philosophical impoverishment, Lord Kṛṣṇa has mercifully instructed them in the Bhagavad-gītā (B.G.7:19),

bahūnāṁ janmanām ante
jñānavān māṁ prapadyate
vāsudevaḥ sarvam iti
sa mahātmā su-durlabhaḥ

After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare.
As the saying goes, "A tethered cow goes as far as the rope." Similarly, one who uses the inductive method to search for ultimate knowledge will fail. His attempt is futile because one cannot know the supramundane with a mundane mind. Complete comprehension of the Absolute Truth is impossible with an unholy, demoniac mind. When one is possessed of a demoniac mentality that tries to reduce the supremely omnipotent Personality of Godhead to impersonal Brahman, all so-called philosophical debates will fail to discover the realm of absolute knowledge or the truth about the nondual substance. Vaiṣṇavas alone are eligible to cultivate such knowledge.

As fire in the forest immediately burns to ashes an angry snake, so, by the previous order of the Supreme Personality of Godhead, His disc, the Sudarśana cakra, immediately burnt to ashes the created demon to protect the Lord's devotee.

As a pure devotee, Mahārāja Ambarīṣa, although in such danger, did not move an inch from his position, nor did he request the Supreme Personality of Godhead to give him protection. He was fixed in understanding, and it was certain that he was simply thinking of the Supreme Personality of Godhead in the core of his heart. A devotee is never fearful of his death, for he meditates on the Supreme Personality of Godhead always, not for any material profit, but as his duty. The Lord, however, knows how to protect His devotee. As indicated by the words prāg diṣṭam, the Lord knew everything. Therefore, before anything happened, He had already arranged for His cakra to protect Mahārāja Ambarīṣa. This protection is offered to a devotee even from the very beginning of his devotional service. Kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (B.G.9:31). If one simply begins devotional service, he is immediately protected by the Supreme Personality of Godhead. This is also confirmed in Bhagavad-gītā (B.G.18:66): ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi. Protection begins immediately. The Lord is so kind and merciful that He gives the devotee proper guidance and all protection, and thus the devotee very peacefully makes solid progress in Kṛṣṇa consciousness without outward disturbances. A serpent may be very angry and ready to bite, but the furious snake is helpless when faced by a blazing fire in the forest. Although an enemy of a devotee may be very strong, he is compared to an angry serpent before the fire of devotional service.
(Srimad Bhagavatam-9:4:48--translation and purport).

There is another instance of ecstatic love for Kṛṣṇa in friendship. Once when a cowherd boy named Vṛṣabha was collecting flowers from the forest to prepare a garland to be offered to Kṛṣṇa, the sun reached its zenith, and although the sunshine was scorching hot, Vṛṣabha felt it to be like the moonshine. That is the way of rendering transcendental loving service to the Lord; when devotees are put into great difficulties—even like the Pāṇḍavas, as described above—they feel all their miserable conditions to be great facilities for serving the Lord.
