Srimad Bhagavatham 11:3:22
तस्माद् गुरुं प्रपद्येत जिज्ञासुः श्रेय उत्तमम् |
शाब्दे परे च निष्णातं ब्रह्मण्य् उपशमाश्रयम् ||
तत्र भागवतान् धर्मान् शिक्षेद् गुर्व्-आत्म-दैवतः |
अमाययानुवृत्त्या यैस् तुष्येद् आत्मात्म-दो हरिः ||
Srimad Bhagavatham guides those seeking real happiness to surrender to a Guru who has realised the ultimate reality.
What should one learn from that Guru ?
Srimad Bhagavatham adds that one should learn Bhagavatha Dharma (which is nothing but chanting of the Divine Name of God) from such a Guru by which Sri Hari is pleased.

The Sanathana Dharma is universally true. While the Dharma cannot be changed, the alternative is to adapt the right kind of Dharma, apt for the age. That is verily the Bhagavata Dharma, which is nothing but chanting of the Divine Name of God
All those who are associated with this Sath Sangam should lead the life of Dharma; should do Naama Japam and Naama Sankirtanam every day; should be ever helpful to one and all; should be disciplined and in control always.
