Mahaprabhu the perfect teacher .

In spiritual life, we must always follow the perfect examples . Many holy teachers can be given as excellent examples to follow . In the Srimad Bhagavatam, one can particularly hear of those examples and the of the devotees’ who executed them.
This verse can be studied in details.
sakhyam ātma-nivedanam
Hearing and chanting about the transcendental holy name, form, qualities, paraphernalia and pastimes of Lord Viṣṇu, remembering them, serving the lotus feet of the Lord, offering the Lord respectful worship with sixteen types of paraphernalia, offering prayers to the Lord, becoming His servant, considering the Lord one’s best friend, and surrendering everything unto Him (in other words, serving Him with the body, mind and words)—these nine processes are accepted as pure devotional service
Sri Caitanya Mahāprabhu has given us a demonstration in His life and pastimes of how in this age these important processes are carried out simply and practically , He perfectly carried out all of them personally, thus He is the perfect teacher who teaches by example.
The following verse indicates He is the perfect teacher , and Srila Bhaktivinod Thakur indicates Mahaprabhu is the perfect Guru .

Translation
“Let me take shelter of the Supreme Personality of Godhead, Śrī Kṛṣṇa, who has descended in the form of Lord Caitanya Mahāprabhu to teach us real knowledge, His devotional service and detachment from whatever does not foster Kṛṣṇa consciousness. He has descended because He is an ocean of transcendental mercy. Let me surrender unto His lotus feet.
AC Bhaktivedanta Swami Prabhupada would indicate any of the nine processes if perfected can carry one to the spiritual worlds , so a very broad sweeping approach to those who practice spiritual life can be adopted and during the natural development of spiritual life and as we get older some of those proccess may be more prominent.
Srila Bhaktisiddanta Sarasvati Goswami Maharaja was the founder of a large institution but would spend much time alone in writing and deep meditation.
