We should always remember that a person who is reluctant to accept a spiritual master for initiation is sure to become baffled in his endeavour to go back to Godhead. Such person who is not properly initiated may present himself as a great devotee but in fact he is sure to encounter many many stumbling blocks on his way of progressive march towards spiritual realisation and the net result is that he has to continue the term of his material existence without any relief. Such helpless person is compared with a ship without a rudder as such a careless ship cannot reach her destination. It is imperative therefore to accept a spiritual master if at all anyone desires to gain the favour of the Lord. Service of the spiritual master is esse
directly (2)
tāṅdera caraṇa-sevi-bhakta-sane vāsa
One's aim of life should be to serve the ācāryas. Ācārya upāsanam. So our ācārya in the Gauḍīya Vaiṣṇava Sampradāya, the śrī-rūpa sanātana bhaṭṭa-raghunātha, śrī-jīva gopāla-bhaṭṭa dāsa-raghunātha, the Six Gosvāmīns, and if we associate with them... this book, Nectar of Devotion, Bhakti-rasāmṛta-sindhu, if you read regularly, try to understand, this means you are associating with Śrīla Rūpa Gosvāmī directly. And if you act accordingly, then you are serving their lotus feet."
Srila Prabhupada The Nectar of Devotion Vrndavana, October 20, 1972
NOTE: So similarly if we read Prabhupada's books regularly and try to understand, then we are associating with Srila Prabhupada directly. And if we act accordingly, then we are serving His lotus Feet...As Prabhupada often says "Where is the difficulty?"
Jaya Srila Prabh
