In the Padma purāṇa it is said:
na śūdrā bhagavad-bhaktās te tu bhāgavatā matāḥ
sarva-varṇeṣu te śūdrā ye na bhaktā janārdane
"A devotee should never be considered a śūdra. All the devotees of the Supreme Personality of Godhead should be recognized as bhāgavatas. If one is not a devotee of Lord Kṛṣṇa, however, even if born in a brāhmaṇa, kṣatriya or vaiśya family, he should be considered a śūdra."
(Sri Caitanya Caritamrta----3:16:29----purport).

In the Padma Purāṇa it is also said:
śva-pākam iva nekṣeta loke vipram avaiṣṇavam
vaiṣṇavo varṇo-bāhyo ‘pi punāti bhuvana-trayam
"If a person born in a brāhmaṇa family is an avaiṣṇava, a nondevotee, one should not see his face, exactly as one should not look upon the face of a caṇḍāla, or dog-eater. However, a Vaiṣṇava found in varṇas other than brāhmaṇa can purify all the three worlds."
The Padma Purāṇa further says:
śūdraṁ vā bhagavad-bhaktaṁ niṣādaṁ śva-pacaṁ tathā
vīkṣate jāti-sāmānyāt sa yāti narakaṁ dhruvam
"One who considers a devotee of the Supreme Personality of Godhead who was born in a family of śūdras, niṣādas or caṇḍālas to belong to that particular caste certainly goes to hell."
(Sri Caitanya Caritamrta----3:16:29----purport).

In the Padma Purāṇa it is stated that just as Rādhārāṇī is dear to Kṛṣṇa, similarly the kuṇḍa known as Rādhākuṇḍa is also very dear to Him. Rādhārāṇī is the only gopī who is dearer to Kṛṣṇa than all the other gopīs. In Śrīmad-Bhāgavatam (10.30.28) it is also stated that Rādhārāṇī and the gopīs render the highest perfectional loving service to the Lord and that the Lord is so pleased with them that He does not wish to leave the company of Śrīmatī Rādhārāṇī.

In the Padma Purāṇa it is stated, "For one who has given up his material sense enjoyment and has accepted the principles of devotional service, the opulence of Viṣṇuloka (the kingdom of God) is awaiting."
(Nectar of Devotion).

In the Padma Purāṇa it is said, "Kṛṣṇa, or Hari, is the master of all demigods, and therefore He is always worshipable. But this does not mean that one should not offer respect to the demigods."
(Nectar of Devotion).

In the Padma Purāṇa it is stated that even a person whose life is completely sinful will be completely protected by the Lord if he simply surrenders unto Him. So it is accepted that one who surrenders unto the Supreme Personality of Godhead becomes free from all sinful reactions. And even when a person becomes an offender unto the Supreme Personality of Godhead Himself, he can still be delivered simply by taking shelter of the holy names of the Lord: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. In other words, the chanting of Hare Kṛṣṇa is beneficial for eradicating all sins, but if one becomes an offender to the holy names of the Lord, then he has no chance of being delivered.

In the Padma Purāṇa it is said, "The Lord may offer liberation or material happiness to a devotee, but after some devotional service has been executed, particularly in Mathurā during the month of Kārttika, the devotees want only to attain pure devotional service unto the Lord." The purport is that the Lord does not award devotional service to ordinary persons who are not serious about it. But even such unserious persons who execute devotional service according to the regulative principles during the month of Kārttika, and within the jurisdiction of Mathurā in India, are very easily awarded the Lord's personal service.
(Nectar of Devotion).

In the Padma Purāṇa it is stated that King Bhagīratha was the emperor above all other kings, yet he developed such ecstatic love for Kṛṣṇa that he became a mendicant and went out begging even to the homes of his political enemies and untouchables. He was so humble that he respectfully bowed down before them.
(Nectar of Devotion).

In the Padma Purāṇa it is said that there are 900,000 species of life in the water, 2,000,000 species of plants, 1,100,000 species of insects and reptiles, 1,000,000 species of birds, 3,000,000 species of beasts, and only 400,000 species of human beings. So the humans are the least numerous species of all.
