The entire universe is full of miseries, and therefore the inhabitants of this material universe are always shedding tears out of intense grief. There is a great ocean of water made from such tears, but for one who surrenders unto the Supreme Personality of Godhead, the ocean of tears is at once dried up.

His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 3.28.32, Purport

A person who accepts the path of devotional service is not bereft of the results derived from studying the Vedas, performing austere sacrifices, giving charity, or pursuing philosophical and fruitive activities. Simply by performing devotional service, he attains all these, and at the end he reaches the supreme eternal abode.

Lord Sri Krsna
Bhagavad-gita 8.28

The holy name of Hari [Krsna] is the essence of the Vedas and far superior to them. One of Krsna's names is om, the seed from which the Vedas have sprouted. One who continuously chants Lord Krsna's names is considered to have mastered the fourVedas.

Srila Jagadananda Pandita
Prema-vivarta, Chapter 20

It is My vow that if one only once seriously surrenders unto Me, saying, "My dear Lord, from this day I am Yours," and prays to Me for courage, I shall immediately award courage to that person, and he will always remain safe from that time on.

Lord Sri Ramacandra
Ramayana (Quoted in Caitanya-caritamrta, Madhya 22.34)

O my Lord, best of the givers of benediction, if You at all want to bestow a desirable benediction upon me, then I pray from Your Lordship that within the core of my heart there be no material desires.

Sri Prahlada Maharaja
Srimad-Bhagavatam 7.10.7

A person fit for residence in hell can easily become a devotee of the Lord by chanting Lord Krsna's names. He can then enter the highest spiritual abode of the Lord.

Nrsimha Purana

It is the duty of every living being to perform welfare activities for the benefit of others with his life, wealth, intelligence, and words.

Lord Sri Krsna
