​What is Diksha and its significance?

Types of Diksha and auspicious Muhurta to take Diksha.​

Diksha is a samskara (a purificatory ceremony or rite marking a major event in one’s life​)​​ ​involved in all serious Spiritual learning. It is a spiritual practice having the ability to provide divinity to a native and to destroy the sins  (त्रिविध पाप ) of a native.

Diksha is a special practice (क्रिया विधि), done by a capable Guru to inculcate divinity in the thought process and to destroy the blemishes of the thoughts of a student.

The seed alphabets (वर्ण) or group of alphabets (वर्ण समूह) whose pronunciation and contemplation protects (त्राण,रक्षण) the native from the 3 kinds of fears  (Daihik or दैहिक, Daivik or दैविक, Bhautik or भौतिक) are called Mantra.
Diksha gets this special ability from Mantras and hence the two have inseparable bonding.

Diksha (दीक्षा) is of 3 kinds:

​​Aaavani (आवणी), Shaakti (शाक्ती) and Shambhavi (शाम्भवी).

Aaavani (आवणी) Diksha is also called Mantra Diksha (मंत्र दीक्षा), Shaakti and Shaambhavi Diksha are also called Vedh Disha (वेध दीक्षा).

1. In Aavani (आवणी) or Mantra Diksha (मंत्र दीक्षा), the Guru with his powers enters into the student and by following a prescribed process establishes swar,sparsh and vyapak varn in every part of the student’s body, comprehensively and makes his body pure. It means that the Guru establishes the letter, vowels and consonants in the entire body of the student. After then, hawan and other rituals are done and the Guru gives the Mantra to the student.

2. Shaakti Diksha (शाक्तीदीक्षा) : Is of 4 types. Chaksushi (चाक्षुषी : via eyes), Sparshi (स्पार्शी : via touch), Vachik (वाचिकी: via words) and Manasi (मानसी : via mental power).
In this Diksha, the Guru enters his energies via sight, touch, word, or mind into a student and awakens his Kundalini Shakti (कुण्डलिनी शक्ति), thereby providing Divinity to the body.

3. Shaambhavi Diksha (शाम्भवी दीक्षा): is considered most acute and quick in which the Guru in the Diksha Kaal only makes the shishya realize the Jeeva & Brahmaikya and makes hum Jeevan Mukta (जीवन मुक्ता: one free from wordily bondages).

Diksha also brings the unison of the Guru with the student. It involves giving of a Mantra or an initiation by the Guru (a Siddha or knowledgeable one or who has experienced truth).

The Guru speaks the Mantra in the right ear (3rd house) of the student and when the student chants it, the learning begins via the 5th house or via the Mantra bhava
Devotion and emotional purity (5th house) in a student are prerequisites for meaningfully obtaining Diksha. So that their mind stays in tune with that of Guru and they remain focused to eventually transform the seed ‘of Mantra’ into a tree and attain All-Mighty (Ishwar). It is the real protection of the mind which is Mantra gives.
