Answer: Your observation in the book “They lived with God” is correct. It is only those who are of the level of an incarnation can recognize another incarnation, unless one reveals himself. In the modern days there is no depth of fake god-men which makes it all the more difficult to recognize. I feel if we have true devotion to the incarnation of the God as Sri Ramakrishna is sufficient for our spiritual progress, instead of our trying to judge an incarnation person.

The state of Nirvikalpa Samadhi cannot be expressed. It is a thing to be experienced. There may be some who have experienced. But it is difficult to say whether they will give expression to it, even if they do it, they do so only to another competent person who will be able to comprehend.
Under the circumstances it is more desirable for to do our spiritual practice. To the best of our ability as guided by our Guru & other scriptures.

Answer: Astrology is a science. There are some people who can predict the things ” past & future ” of person on the basis of their date & time of birth. But unfortunately there are more quacks than the real ones.
The predictions of the past may tally. But it is not necessary that the future predictions will also tally. The man is the maker of his own destiny. When we know certain things, we can take corrective measures. The self effort and Divine grace can alter the course of a person. This is how the man evolves. Simply to say that it is fate is only a weakness.

Answer: Please read the book The Sri Ramakrishna – The Great Master by Swami Saradananda (Apostle of Sri Ramakrishna) published by Sri Ramakrishna Math, Mylapore, Chennai – 600 004 Pp. 334-336. The relevant extract is appended.

            Extract from the Sri Ramakrishna - The Great Master by Swami Saradananda 
            Preparations for the worship of Shodasi:
            A little more than half of the month of Jyaishtha, B.E 1280 (A.D. May 25,1873) had elapsed.
            It was the new-moon day, the holy occasion for the worship of the Phalaharini Kalika Devi. It was the day of a special festival at the
            Dakshineswar temple. The Master had made special preparations on that day with a view to worshipping the Mother of the universe. These
            preparations, privately, in his own room at his desire. A wooden seat painted with Alimpana, the pigment of rice powder, for the Devi to
            sit on at the time of worship, had been placed to the right of the worshipper. The sun had set. The now-moon night, veiled in deep
            darkness, had alighted on the earth. Hriday, the Master's nephew, had to perform a special worship of the Devi in the temple. He had,
            therefore, helped as much as possible in the preparations for the Master's worship and had gone away to the temple. Having finished the
            nocturnal service and worship of Radha-Govinda, the first priest, Dinu, came to help the Master in the preparations. It was 9 p.m. when
            all the preparations for the mystery-worship of the Devi were completed. In the meantime, the Master had sent word to the Holy Mother to
            be present during-the worship. She came to the room and the Master started the worship. The Holy Mother worshipped as the Deity
            The articles of worship were purified by the Mantras and all the rites preliminary to the worship were finished. The Master beckoned to
            the Holy Mother to sit on the wooden seat decorated with the Alimpana. While witnessing the worship, the Holy Mother had already entered
            into a divine semi-conscious state. Not clearly conscious, therefore, of what she was doing, she like one charmed with Mantras, sat facing
            north to the right of the Master, who was seated with his face to the east. According to scriptural injunctions the Master sprinkled the
            Holy Mother repeatedly with the water purified by Mantras from the pitcher placed before him, then uttered the Mantra in her hearing and
            then recited the prayer: 
            "O Lady, O Mother Tripurasundari who art the controller of all powers, open the door to perfection! Purify her (the Holy Mother's) body
            and mind, manifest thyself in her and be beneficent."  
            Afterwards the Master performed the Nyasa of the Mantras in the Holy Mother's person according to the injunctions of the Sastras, and
            worshipped her with the sixteen articles, as the Devi Herself. He then offered food and put a part of it into her mouth with his own hand.
            The Holy Mother lost normal consciousness and went into Samadhi. The Master too, uttering Mantras in the semi-conscious state, entered
            into complete Samadhi. The worshipper in Samadhi became perfectly identified and united with the Devi in Samadhi. 
            A long time passed. The second quarter of the night was over and the third had far advanced, when the Master, whose delight was, only in
            the Self, showed a little sign of regaining normal consciousness. Returning to the semi-conscious state again, he offered himself to the
            Devi. He now gave away for ever at the lotus feet of the Devi his all -- the results of his Sadhanas, his rosary etc.-- along with his
            self, and saluted her, uttering the Mantras: 
            "O Thou, the auspiciousness of all auspicious things! O door of all actions! O refuge! O the three-eyed One! O the fair complexioned
            spouse of Siva! O Narayani! I bow down to Thee, I bow down to thee! " 
            The worship was at an end.1 The Master's Sadhana reached its culmination with the worship of the Ruler of the universe, the Divine Mother
            in the body of a woman, the embodiment of spiritual knowledge itself. The god-man attained perfection in all respects. 

Answer: According to Hindu scriptures, Brahman – the Divine Supreme – projected this universe – first cosmic, then organic, at various levels of evolution. He was not satisfied with all these animals, serpents, fish, trees, etc. because He would not be able to rediscover Himself. So He projected the human form in which He could rediscover Himself. This is the greatness and uniqueness of human birth; one can manifest one’s divinity. The various paths are described for this purpose. The journey through these paths is known as spiritual life . Meditation is one of the higher steps of spiritual life. You read the following two books, where you can get a detailed idea:

1) Meditation and Its methods by Swami Vivekananda

2) Meditation and Spiritual Life by Swami Yatishwarananda
