But if one just enters into the spiritual life and wants to realise God without the help of a Master, it is impossible. For an ordinary human being, hundreds and thousands of incarnations are required. Even if one has a good Master, if the disciple is not one hundred per cent sincere, it may take six, seven, ten or twenty incarnations. But the very best disciples get realisation either in one incarnation or in a few incarnations, under the constant guidance of the Master.
Occasionally someone realises God without having a spiritual Master. How is it possible? In his past incarnation, perhaps he had a very, very powerful Master. In this incarnation his Master has not taken human incarnation, but from the inner world this Master is constantly guiding him, moulding him and instructing him. The seeker knows that his Guru is instructing him during his dreams and during his meditation.
Then, of course, there is also another possibility. If a seeker has been meditating for quite a few incarnations and God is most pleased with him, and if the seeker is not favoured with a spiritual Master in this incarnation, then God Himself plays the part of a spiritual Master, even during the seeker’s waking hours and in his day-to-day life activities. If the seeker needs to drink a glass of water, God will tell him, “Go and drink a glass of water.” And if he has to shut the windows, God will tell him. God will take the form of a very, very luminous being and will guide him in this way.From:Sri Chinmoy,The summits of God-Life: Samadhi and Siddhi, Agni Press, 1974
