Why the path of Bhakti and the path of Raj (Siddha) not effective now-a-days ?

There is no clear cut demarcation among Bhakti path, Raj (Siddha) path and Gyan path. Every path contains qualities of all the paths but in different ratio. The name is assigned on the basis of dominance of qualities of the path being given name. The requirements/qualities in the person taking the various paths are as under:

1. Bhakti- Important requirements are-Innocence like child, simplicity and trusting mind.

1. Raj (Siddha) -- Important requirements are- Availability of enough spare time for asnas, pranayama, meditation, etc. as expounded by Patanjali. A fixed calm place for sadhna. Following a rigorous discipline as given by the Guru. There is always a chance to go astray if a real Master of Siddha tradition is not the Guru. This path is capable of giving rise to Spiritual Ego (especially when siddhies start manifesting) which is more dangerous and powerful than the normal ego.
2. Gyan – (direct path) -- Important requirements are- Study of various scriptures, discussion with the fellow travelers and Masters (like Upanishadic Era), etc. with utmost consciousness. Remaining conscious is the key.
3. In this era of science the mind is doubtful in nature and is full of informations due to various reasons. We are so attached to the mind that the mind is behaving like master instead of servant of this body who took it for its smooth survival. The mind/person does not remain simple at all. The innocence is not seen in the waking state at all. The question of trust does not arise. Therefore surrendering does not happen effortlessly. The so called surrendering is no surrendering at all. However exception may be there. In the name of trust only belief and faith are existing. Hence Bhakti path in not effective as it is not suitable for almost all the persons in this yuga/era

So ar as the Siddha path is concerned this is the most difficult path to be followed due to the requirements/preconditions mentioned above. Nobody has enough time for sadhna or a calm suitable place for that. Scarcity/unreliability of real guru of Siddha tradition is already there.

Hence the most suitable path in this era of science is nothing but undoubtly the Gyan path. The basic programme of the mind is logic. In this path mind which is the only instrument available for all the paths, is used at maximum.
