Whatever a person may be in the estimation of the social order of things, if a person tries to reciprocate a feeling of love towards the Supreme Personality of Godhead and is satisfied with the blessings of the Lord, he will at once feel the highest peace of mind for which he is hankering life after life.
His Divine Grace A.C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 2.6.6, purport
Anyone trying to enumerate or describe fully the unlimited qualities of the unlimited Supreme Lord has the intelligence of a foolish child. Even if a great genius could somehow or other, after a time-consuming effort, count all the particles of dust on the surface of the earth, such a genius could never count the attractive qualities of the Personality of Godhead, who is the reservoir of all potencies.
Sri Drumila
Srimad-Bhagavatam 2.6.6
What assurance of real happiness is there in all of one's wealth, youthfulness, sons, and family members? This life is tottering like a drop of water on a lotus petal; therefore you should always serve and worship the lotus feet of Lord Krsna.
Govinda Dasa Kaviraja
Bhajahu Re Mana Sri Nanda-nandana
The manifestation of unadulterated devotional service is exhibited when one's mind is at once attracted to hearing the transcendental name and qualities of the Supreme Personality of Godhead, who is residing in everyone's heart. Just as the water of the Ganges flows naturally down towards the ocean, such devotional ecstasy, uninterrupted by any material condition, flows towards the Supreme Lord.
Lord Kapila
Srimad-Bhagavatam 3.29.11-12
To say nothing of the spiritual advancement of persons who see the Supreme Person face to face, even a person born in a family of dog-eaters immediately becomes eligible to perform Vedic sacrifices if he once utters the holy name of the Supreme Personality of Godhead or chants about Him, hears about His pastimes, offers Him obeisances, or even remembers Him.
Srimati Devahuti
Srimad-Bhagavatam 3.33.6
The spiritual master is to be honored as much as the Supreme Lord, because he is the most confidential servitor of the Lord. This is acknowledged in all revealed scriptures and followed by all authorities.
